CHAPTER 2
GENETICS
A WORD ON SEQUENCING
ОглавлениеDNA and RNA discovery gave science a powerful impetus to find reliable ways to sequence nucleotides. They are all united by a generic term – sequencing.
Sequencing technologies bring us closer to the future of genomic medicine. The deciphering of the genetic code has opened unprecedented prospects for scientists and physicians and has made it possible to solve many applied and fundamental problems: the development of new medicines, vaccines, and other products. Sequencing technologies not only help identify deep-seated diseases, but also allow us to learn more about the evolutionary history of humans, animals, and plants, as well as understand the causes of mass extinctions on Earth. By sequencing the genomes of the remains, scientists learn about the origin of species, the body age, and habitat conditions. By studying DNA fragments, scientists identified a new species of ancient people, the Denisovans[26].
Initially, sequencing was a very expensive method and only very rich people and organizations could afford it. Today, almost every scientific or medical laboratory can order or perform this procedure independently. Many companies are performing genetic testing and offering individualized recommendations to help improve health and prolong life. If you know that one of the genes is defective, you can mitigate its harm in different ways, such as lifestyle adjustments or drug therapy. This personalized approach is more advanced than the current level of medical development and is undoubtedly useful for the aging research field.
Thus, by reading the genome, it is possible to unlock the secrets of longevity encoded in it and change human life for the better by activating the "immortality genes" and protecting them from damage.
