Fortunately, the majority of them does not bear the functional load and has no impact on human health. The active use of specific genes leads to variation, which is mutation. Most prone to mutations, according to scientists from the Medical Institute of Howard Hughes, the most used genes. About it writes the Internet-the portal India.com.
The researchers identified 36 genes from the nerve cells of people who died not from disease of the brain. As comparison was used the genetic material of cells of the heart these same people. "Genetic Bank" of each neuron was unique, scientists in the study found about thousands of small mutations in the genome. None of them affect the work of the brain throughout a person's life.
Most mutations in neurons appeared due to the active genes. The mutation became a mechanism of gene protection from wear and played a crucial role in maintaining the function of the individual cells.
