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 all important(predicate) commonplace health goals: extending good health well into grey-headed age. These caps ar called telomeres, and theyre at the center of much of the current look into the age process. A guinea pig recently published in scientific discipline journal The Lancet links the lengths of telomeres with run of survival among tidy sum over 60, the first study to make this connection. What are Telomeres? To jockstrap understand the role telomeres institute within the humans body, its utilitarian to review some rudimentary biology. All of the tissues within the human body are make up of individual cellphoneular telephones. These cells comprise chromosomes within their nuclei. Chromosomes are the packages that patronise most of our desoxyribonucleic acid - the familial instructions that promulgate the cell what to do. Telomeres are reiterateing desoxyribonucleic acid sequences at the ends of the chromosomes. They do not 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 more as 20,000 base pairs of DNA. What do Telomeres do? Telomeres are suasion to serve a parallel of purposes within human cells. One, the telomeres manikin end caps for their chromosomes.

Without them, the body would need no way to retire where the chromosomes ended. It would treat them as befuddled pieces of DNA and would attem pt to make them by joining them with separ! ate chromosomes. With telomeres, the 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
