Chapter 788 What is a gene? Gene editing
What is a gene?
Decades ago, probably very few people would have been able to answer this question.
However, nowadays, most people can give a detailed explanation.
Even without a high level of education, one can still utter the saying, "Like begets like."
This statement is actually a manifestation of biological genetic inheritance.
When Wang Donglai, still aboard the spaceship, shifted the topic to the research and development direction of Galaxy Bio, even netizens who weren't particularly interested but were only there for the ten million yuan cash prize in this live stream became more interested.
"What are genes?"
"Many people can answer this question without even searching online."
"In high school biology class, we learned that a gene is the general term for a specific nucleotide sequence on a DNA (deoxyribonucleic acid) molecule (the genetic material of some viruses, such as tobacco mosaic virus and HIV, is RNA), which has a genetic effect. It is a DNA molecule segment with a genetic effect."
"Leaving aside those official grand principles, let's use the simplest example: a golden retriever who is a gentle and kind man and a husky who loves to joke. The mixed-breed 'golden husky' that they produce will have more of the golden retriever's dominant genes and less of the husky's."
According to contemporary scientific research, genes only account for 2% to 4% of the total DNA mass.
"Don't underestimate its small amount; its number is not to be underestimated. A simple life form requires at least 265 to 350 genes. For example, a yeast that is invisible to the naked eye has about 6000 genes; a tiny roundworm has about 1.9 genes."
"The human genome contains approximately 2 to 3 genes. These genes are the chemical codes necessary for the formation of the human body, storing all the information about the processes of human life, such as race, blood type, conception, growth, and death, and governing the entire life journey of an organism from birth to death."
"At this point, some people might think I'm about to talk about the importance of human genes."
"However, I'm going to tell you a little-known fact."
"That means biological genes can be described as ancestral mountain of code, just like programmers writing code, which is always just piling on top of it, rather than rebuilding and constructing it."
"The same is true for the genes in our bodies. In the nearly one hundred trillion cells in the human body, each cell's DNA code has three billion base pairs. If all the DNA in the human body were connected end to end, its length would be equivalent to more than 600 times the distance from the Earth to the Sun. In such a huge genetic code, the probability of finding two genes with completely identical sequences is almost zero. Even identical twins will have different genetic codes."
"Of all these genes, more than half are useless or outdated. There are repetitive junk segments like the Alu sequence, genetic code left over from ancient viral invasions, and redundant modules like the olfactory gene that have been copied more than a thousand times but are mostly ineffective."
"There are more than 20,000 'pseudo-genes' lying in our bodies, just like old functions that have been commented out in the code."
"The vitamin C synthesis gene inherited by mammals was still usable in the monkey era, but it became useless after they came to earth, but it will remain in their bodies."
"According to research, gill slits and tail bones also appear in the early stages of human embryonic development. These genetic codes, which are no longer useful, have not been deleted."
"In other words, if one day, someone's genes suddenly mutate, these previously dormant recessive genes become dominant genes, and the coccyx and gill slits will appear."
"Take our retina, for example. From a scientific point of view, it is obvious that it is installed backwards. The photoreceptor cells are hidden behind the neural circuits, which results in our eyes having blind spots from birth."
"This was a bug in the initial design. To fix it, a bug patch was added later, which included the ability to automatically repair images by slightly moving the eyeballs left and right. The brain also had to allocate a special area to provide computing power to process the vision of blind spots."
"For example, we share the same passage for breathing and eating. If we are not careful, we will choke. People often die from choking. If this design were in the engineering field, it would have been criticized to death long ago. But in biology, it can only be used as a makeshift solution. At most, we can add an epiglottis to block it."
"Because the human body is not comfortable with engineered products, the design can be restarted from scratch, so we can only make compromises."
"A similar case is the recurrent laryngeal nerve, which has to go around under the heart and blood vessels before turning back to control the vocal cords, turning a 5-centimeter direct connection into a 30-centimeter one, making it so long that even swallowing is delayed. This is purely because this nerve was originally designed for our fish ancestors, but who could have imagined that the descendants of fish would have such long necks, especially giraffes, whose recurrent laryngeal nerves can be more than four meters long, making them arguably the most overworked recurrent laryngeal nerves in the biological world."
"Even though deleting two lines of legacy code would allow for a direct connection, evolution is afraid to touch the old architecture and instead chooses to overlay hot patches. As a result, when performing thyroid surgery, doctors have to be extremely careful not to damage this bypass nerve, because if it is damaged, the patient will immediately become mute."
"Eukaryotes insist on using exons and introns. To read a gene, you have to cut off 40% of the non-coding region. It's like inserting a lot of nonsense into code and then writing a preprocessor to filter it."
"Not to mention the weird practices of epigenetics. Even though the DNA code is the same, they still have to rely on 'annotation symbols' like methylation to determine which codes take effect. It's like using metaphysics to maintain the ancestral mountain of shit."
"..."
When Wang Dong was talking about these things, many netizens who had some knowledge of biomedicine immediately had a word come to mind.
Gene editing!
Because what Wang Donglai said is the same as what those scholars who advocate gene editing say.
However, just recently, He Kui caused a huge uproar because of gene-edited babies. He was found to have carried out human embryo gene editing activities for reproductive purposes, which are expressly prohibited by the state. He was directly detained and sentenced to three years in prison and fined three million yuan this month.
The speed at which this was done demonstrates the severity of the crackdown from above.
Therefore, when many people heard what Wang Donglai said and thought of He Kui's matter, their expressions changed immediately.
However, what everyone else could think of, Wang Donglai naturally understood as well.
Technology itself is not wrong; people are wrong.
Just as a doctor invented the machine gun, hoping to end the battle faster and better, but instead the war intensified.
"Many people might think that Galaxy Bio is conducting similar gene editing research when they hear this."
"That's a wrong guess!"
"Galaxy Bio's research and development is based on ethics and law. Researching genes is also to better unravel the mysteries of the human body."
"Just like the Evergreen Liquid we developed, it is a qualified and successful product."
"It is precisely because we have a deeper understanding of human genes that we are able to develop special ingredients to promote the secretion of special growth hormones, restore hair follicles, and grow hair."
"The same goes for beauty toners and choleretic and liver-soothing tablets..."
"That's not all; Galaxy Bio is also conducting research and development on a wider range of gene-based drugs."
"Leveraging our breakthroughs in artificial intelligence technology, we have combined medical data from our partner medical institutions to develop a comprehensive intelligent medical system and launched a large-scale internal model."
"Using the massive computing power of AI, we can classify and analyze DNA genetic information."
"If these tasks were done manually, the time and effort required would be enormous."
"But it's different when it's on a machine."
"..."
Wang Donglai recounted many details, providing a comprehensive overview of Galaxy Bio's research and development in biological genes and advanced medical fields.
For example, brain interfaces, neural information transmission, and research on human longevity.
Some technologies sound like magical stories.
However, when Wang Dong said it, not many people questioned it.
soon.
Wang Donglai then changed the subject, mentioning artificial intelligence. As the only true owner of artificial intelligence in the world, Wang Donglai's understanding of AI technology is arguably the deepest and most authoritative.
It's fair to say that if Wang Donglai doesn't understand artificial intelligence, then it's even less likely that anyone else would.
This is almost universally acknowledged by outsiders.
Therefore, when Wang Donglai started talking about artificial intelligence technology, many scholars and experts were mixed in with the audience watching the live broadcast.
Many people are unaware of just how advanced artificial intelligence technology Galaxy Technology possesses.
One can glean some insight from the appearance of even a few scales and claws.
Now that Wang Donglai is finally going to talk about artificial intelligence technology, everyone is naturally eager to take the opportunity to speak.
"The history of artificial intelligence from the 1940s to 2012 has been extensively covered in books and online, so I will not go into detail here."
“Since 2012, artificial intelligence technology has been favored by the Bald Eagle Federation and us, and has also attracted the attention and research of scholars.”
"This is mainly because image recognition technology has been proven to be feasible, and a representative example is that Google and Baidu spent more than $4000 million to competitively purchase the technology developed by three scientists in collaboration."
"This means that machines have 'eyes' and can understand the surface phenomena of human society, thus enabling them to perform many automated identification and detection tasks, replacing human eyes, and even being more efficient and reliable than human eyes."
"Applications in this area include industrial product inspection, facial recognition, video surveillance, and visual navigation."
"But these alone are far from enough to qualify as artificial intelligence technology."
"Because its technology is still very limited, in actual application, its performance is even worse than that of a five-year-old child."
"But!"
At this moment, Wang Donglai's tone suddenly became more assertive.
"When I started researching artificial intelligence technology, I suddenly realized that many of the problems here can actually be solved using mathematics."
"With my talent in mathematics, I quickly completed the first generation of AI-assisted medical diagnosis system. This AI-assisted medical diagnosis system is actually a large model language system."
"..."
Just as Wang Donglai began explaining the technical principles behind Galaxy Technology's artificial intelligence technology.
On the ground, countless scholars watching the live broadcast had their eyes light up.
They watched Wang Donglai intently on the live stream, just like students in a classroom, and took notes of what he said.
The reason for doing this is so that I can study it repeatedly later.
Of course, besides these, many people also recorded Wang Donglai's live stream at this time.
Keep in mind that this is Wang Donglai, a world-leading scientist, explaining artificial intelligence technology.
Even a small amount of knowledge they gain will be extremely important for their future development.
However, just as everyone was listening intently to Wang Donglai's explanation of artificial intelligence technology...
Wang Donglai suddenly threw out a shocking statement at this moment.
"We need to be wary of artificial intelligence technology, and also wary of its overuse!"
The countless people waiting in front of the live stream were all astonished when they suddenly heard this.
No one expected Wang Donglai to say that at this time.
It should be noted that the development of Galaxy Technology has spurred the rapid development of many other technologies in this timeline.
For example, investments in drones, or in the field of artificial intelligence.
Many internet companies, such as Taotian Group and Baidu, invested in artificial intelligence research and development much earlier than the original timeline, with significantly greater research efforts and investment amounts.
But now, Wang Donglai suddenly said this.
Ordinary netizens were just curious, but smart people immediately thought of many things.
Burning bridges across rivers!
Weld the car doors shut after you get in!
This was everyone's first reaction to Wang Donglai's words.
Because everyone acknowledges that Galaxy Technology's artificial intelligence is the most advanced and far ahead of the competition.
Both domestic and international tech giants are catching up.
As a result, Wang Donglai's words seemed to be hindering the development of those who came after them.
To avoid the emergence of competitors that could affect Galaxy Technology's leading position in the field of artificial intelligence technology.
They were no strangers to this method.
Because they also had this idea and were prepared to do so.
After all, monopolies are the most profitable.
Even in the least profitable industry, you can make a fortune if you monopolize it.
Therefore, this was their first thought upon hearing Wang Donglai's words.
That wasn't all. Wang Donglai continued, "I have another idea here, which is to establish an artificial intelligence public platform, or to launch an artificial intelligence public template."
"In the information age, information is a kind of soft gold with enormous value."
"In order to utilize this information and generate value, you must have the right application methods."
"Artificial intelligence technology is a key to unlocking the treasure trove of information."
"Of course, this is not the main reason why I am warning against artificial intelligence technology."
As Wang Donglai narrated, countless people listened intently.
Because at this moment, Wang Donglai had already silently activated one of his acquired skills. (End of Chapter)
