The recent studies of the DNA have discovered that the brain cells break their DNA in order to make it possible for us to learn new information and create memories about past events.
This DNA damage allows expressing a whole range of genes that are known as early-response genes.
These are accountable for different processes that accompany the formation of long-term memories.
However, an ability to damage brain cells seems to deteriorate with age, which consequently leads to degenerative processes occurring in the old brain.
Interestingly, the DNA breaks that lead to the development of Alzheimer’s disease are most significant in the areas of the brain that were accountable for our ability to learn and memorize things.
It was also found out that the ability to repair also subsides with age, which means that our DNA repair system works less effectively as we get older.
However, it is still not known how all these changes happen.
It is known for sure that DNA and genes in the brain cells are accountable for lots of things.
Basically, they influence all the aspects that make us human.
Some of them regulate the process of protein production, while others control biological functions.
One-third of all genes in the human body are active majorly in the brain.
This percentage is the highest of all, and it majorly affects the way our brain functions.
As a result, any changes in the DNA can point out whether we are at risk of some brain disorder or other diseases.
