Programmed Theory of Aging

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...

The Hallmarks of aging

Aging- a Symbolic presentation What are The 9 hallmarks of Aging? According to the scientific world there are 9 reasons behind Aging, they are generally known as 9 Hallmarks of Aging. They are Genomic instability, Telomeres Attrition, Epigenetic Alteration, Loss of Proteostasis Deregulated Nutrient Sensing, Mitochondrial Dysfunction, Cellular senescence, Stem cells Exhaustion and Altered inter cellular Communications. genomic instability Genome is the genetical codes present in organisms. In other words genome is the complete set of DNA present in a cell. Every cell has  copy of the DNA. Genomic instability is the result of high frequency mutations ( sudden changes ) Because of  these mutations chromosome May rearranged, sometime the sequence of nucleic acids  or even the chromosome number May changed,( the chromosome number of human is 23 pairs, or 46 ).  Telomeres attrition Telomeres are the tail ends of chromosomes, which act as protective caps.
