Scientists have identified the gene that can help us live to 100 after studying a group of people with an average age of 97.
They found that the people studied and their children had higher levels of an enzyme called telomerase, known to protect our body’s DNA from degrading.
Telomerase is associated with the formation, maintenance, and renovation of telomeres. Telomere is a region of repetitive DNA at the end of chromosomes, which protects the end of the chromosome from destruction.
Cell division times are correlated with telomere length. After each cell division telomeres get shorter. When telomere shortens to the critical stage, the intensity of cell division significantly decreases, and then cell differentiates and ages.
By boosting telomerase, scientists think they could eventually stop the cells dying and so protect against old age.
