Also important are sequences that do not encode gender

In genetics there is a hypothesis that few question. There are genes that have hardly changed throughout evolution. Natural selection tends to prime important genes without mutating, so it is deduced that the best preserved genes of the species have important functions. But there are other sequences so well preserved on chromosomes that do not encode proteins.

Scientists have said many times that a sequence without gender serves nothing. But by staying so well during evolution they have had to recognize that these sequences can also play an important role. In fact, they are often more stable than the sequences that encode genes, so it is logical to think they will play a role in chromosomes. Some have begun to speculate and have explained that it is possible to participate both in gene regulation and in the organization of DNA.
