All life on earth is encoded in the four letters of DNA, A, T, G, and C. If you stretch the entire DNA chain, its length will reach the sun and go back and forth more than 300 times. In fact, every cell in your body contains DNA. Your DNA is unique in this world. Just like snowflakes, there will not be two pieces that are exactly the same. They are the same as two people who are not exactly the same in the world. Even a pair of twins are not genetically identical.
DNA carries all the instructions for the development, growth and reproduction of life. However, DNA damage may always occur in the cells of our body. In most cases, they do not cause cancer or even mutations, but we know that DNA errors are the root cause of nearly 7,000 diseases. So, if we have the ability to repair them, if we can rewrite the entire human genome from scratch, what will you repair, improve or upgrade?
As we explained in the previous video, the development of biotechnology is so fast that many sciences not long ago were just fictions and hypotheses, but they are now part of our daily lives.
The agricultural sector is editing plant genomes to feed the growing population, expand the scale of production, and produce more delicious and convenient food. The latest advances in genome engineering now allow us to manipulate, customize, and reprogram our genome, thereby enabling us to rewrite our destiny. Artificial intelligence has been used today to study and diagnose a wide range of genetic diseases by reading the human genome. is based on the primary gene transfer experiment , genome editing tools, such as CRISPR Cas system, is revolutionizing the way we modify human cells. , Bacteria capture and use DNA fragments of invasive viruses to produce DNA fragments called CRISPR arrays . These arrangements allow viruses or closely related viruses to remember bacteria. If the virus attacks again, bacteria generate RNA fragments from these arrays to target the virus.
A biochemist from the United States used the find and replace tool in Microsoft Word to describe the similarities of CRISPR technology. You can enter what you want to find in the search box to create an RNA molecule. Search for a specific sequence in the genome.
However, CRISPR is not so precise yet, so we think the best analogy comes from the European Federation of Microbiological Societies. introduce a single letter change or insert without deleting . You can create a complete human genome from scratch. has about 3 billion pairs of nitrogen bases . Although CRISPR technology is still in the early stages of clinical trials and human patients, his main goal is to cure and reverse aging.
Although it is a bit unrealistic to use genetic engineering to never grow old, CRISPR may be the key to preventing age-related diseases.Including, cardiovascular disease, arthritis, cataracts, osteoporotic diabetes, and various cancers.
Due to advances in technology and science, the speed of this progress has even exceeded the expectations of some of the most famous scientists. Many researchers have begun to regard aging as a disease. David Sinclair is a professor in the Harvard Medical School Department of Genetics. He believes that the problem is not whether we can reverse the aging process, but when we can achieve this goal. Although there is no scientific consensus on the disease hypothesis, most experts agree that the way we deal with aging must be changed. If what David said is right, the biggest question we face is is the world ready?
