In this post I want to give you more direct information about your body. I mean DNA.
As I mentioned in one of my previous articles, I will talk to you about how DNA takes care of itself. Every time it regenerates, it does it in the best possible way. Remember that cells regenerate at different times and that they only do so when the body believes it is necessary. Every time they regenerate, they take a bit of our DNA as a base. But over time, the DNA deteriorates and the cells take on that same DNA that is already deteriorated. Therefore, that new cell will not give the same performance.
WHAT IS DNA?
DNA is the chemical name given to the molecule that contains the genetic information in all living things. The DNA molecule consists of two strands that wind together to form a double helix structure. Each chain has a central part made up of sugars (deoxyribose) and phosphate groups. Attached to each sugar is one of the following bases:
The two chains are held together by links between the bases. Adenine binds with thymine, and cytosine with guanine. The sequence of these bases along the chain is what encodes the instructions for making proteins and RNA molecules. DNA contains all the genetic instructions that constitute us, and the maintenance or not of its integrity throughout life is a key, although very complex, part of the aging process.
Recently, scientists at the University of Rochester have discovered a natural DNA preservation mechanism. How wonderful! not?. This would open the possibilities of creating interventions to improve the preservation of genetic information. That means that the damage or loss of the genetic makeup was repressed. With these interventions, diseases that are related to aging could be avoided. Like cancer, or neurodegenerative disorders.
In the Journal of Biological Chemistry, they explain that a process known as acetylation is what regulates the maintenance of DNA. It was previously known that the human being has generated two “pathways” for the replication and repair of genetics. One of these roads would be the “standard” route and the other the “elite” route. The standard way eliminates some damage and a moderate amount of DNA errors, and the elite eliminates the vast majority of genetic errors and damages during DNA replication.
Our body already has that function of repairing our genetics to lead a healthier and longer life. However, specialists have set out to try to help this process and make it more effective. In particular, scientists are analyzing human and yeast cell systems to establish how proteins in cells work in conjunction to activate acetylation. In my next post, I will bring you tips to improve or keep your DNA in better shape with food and habits.
