Aging Image credit pixabay. Com Understanding the Programmed Theory of Aging:A Comprehensive Guide The mystery of Aging has puzzled humans for centuries. While we can't stop time, scientists have explored the theories that explain why we are growing older. One of the prominent idea is The programmed theory of aging, this theory suggest that aging is n't random, instead a process controlled by our gene. The Enigma of Aging:A Biological puzzle Aging is a complex puzzle made up of many pieces. Each piece represent biological changes,environmental factors and life choices. As we try to fit together, we realize that aging involve both our genetics and experiences Programmed Aging:A central Theory in Gerontology Programmed aging proposes that we have a biological clock ticking down through the life. This concept grounded in genetics, implying that our cells are pre-programmed to age and die. This theory stands in contrast to wear and tear theory. Which emphasiz...
Telomere theory of aging Telomere theory of aging was proposed by a Russian scientist A.M.Olovnikov in the year 1971.In the year 1961,an american scientist L.Hayflick discovered that cultured human cells can only divide up to 50 times.On the basis of this discovery and it's data A.M olovnikov studied more and proposed the telomere theory of aging . According to the theory,when the telomeres ( tail end of chromosome ) become too short the cells lose their ability to divide,gradually it lose its efficiency and become aged.After each and every cell division telomeres are unable to be fully copied,therefore they become shorter and shorter.The telomere theory was fully confirmed when an enzyme called telomerase was discovered in 1984, telomerase can maintain the length of telomeres in cancer cells and germ cells ,these cells are devoid of aging and they are immortal.The telomere theory of aging got more popularity when three geneticists, Elisabeth Blackbu...
