Discovered in 1938 by geneticist Hermann J. Müller, telomeres (Greek for «end part») are essentially protective caps composed of short DNA sequences on the tips of chromosomes.
Both aspects center on the critical role of telomeres, protective caps on the ends of chromosomes that erode with age.
The enzyme telomerase maintains the length of telomeres, the protective ends on chromosomes, and most cancer cells use large amounts of the enzyme to ensure their immortality.
This exhaustion of proliferative potential, called senescence, can be triggered when telomeres — the ends of linear chromosomes - can not fulfil their normal protective functions.
LA JOLLA — Ever since researchers connected the shortening of telomeres — the protective structures on the ends of chromosomes — to aging and disease, the race has been on to understand the factors that govern telomere length.
Meditation also helps to protect our telomeres, the protective caps at the end of our chromosomes.
