Scientists have revealed how genes provide cells with "eternal life."

Cells possess a system of virtually unlimited self-repair, enabled by genes—a discovery made by researchers reported in detail on ruposters.ru.

This genetic information, given the necessary resources and protection, is capable of maintaining the viability of cells.

According to scientific and philosophical views, limited lifespan is considered necessary for the evolutionary process, as it facilitates the accumulation of mutations in the genome that are potentially beneficial to subsequent generations. Computer modeling results demonstrate that mortal species have a competitive advantage over immortal ones.

The mechanism of cellular aging is linked to telomeres—the terminal sections of chromosomes that protect DNA from damage. With each cell division, these structures shorten, ultimately depriving the cell of the ability to reproduce further. However, certain stem and germ cells are capable of producing the enzyme telomerase, which restores telomere length, ensuring their potential immortality.

In real-life settings, telomere shortening is accelerated by lifestyle and environmental factors, as confirmed by studies involving monozygotic twins. Psychoemotional state also influences the rate of aging.

Maintaining cellular functionality requires energy resources (glucose and oxygen), mitochondria, building blocks (amino acids, fatty acids), and protection of genetic material. Factors that accelerate aging include chronic stress, lack of sleep, unhealthy habits, an unbalanced diet, low physical activity, and unfavorable environmental conditions.

Slowing down the aging process can be achieved by consuming antioxidants, practicing detoxification, having regular medical checkups after 40, and maintaining physical, intellectual, and social activity.
