Telemeres and the aging effect

The tiny caps that keep our chromosomes from fusing together ar also providing clues that could at last lead to the achievement of one our nations most chief(prenominal) commonplace health goals: extending good health well into obsolete age. These caps are called telomeres, and theyre at the center of much of the current look into the age process. A orbit recently published in scientific discipline journal The Lancet links the lengths of telomeres with enjoin of survival among tidy sum over 60, the first study to make this connection. What are Telomeres? To jockstrap understand the role telomeres mash within the humans body, its utilitarian to review some grassroots biology. All of the tissues within the human body are do up of individual jail electric cells. These cells comprise chromosomes within their nuclei. Chromosomes are the packages that match most of our desoxyribonucleic acid - the familial instructions that ordain the cell what to do. Telomeres are echoing desoxyribonucleic acid sequences at the ends of the chromosomes. They do non contain any genetic instructions; they simply repeat a sequence of DNA over and over. When we are young, the telomeres are very long - they whitethorn contain as many as 20,000 base pairs of DNA. What do Telomeres do? Telomeres are feeling to serve a parallel of purposes within human cells. One, the telomeres bound end caps for their chromosomes.

Without them, the body would need no way to populate where the chromosomes ended. It would treat them as befuddled pieces of DNA and would attempt to make up them by joining them w ith separate chromosomes. With telomeres, t! he body can tell where one chromosome ends and another begins. Second, scientists hypothesise that telomeres may serve as genetic clocks. As we germinate and age, our cells divide. One parent cell divides into two daughter cells, reservation copies of... If you want to get a full essay, order it on our website: BestEssayCheap.com
