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 heavy commonplace health goals: extending good health well into grizzly age. These caps ar called telomeres, and theyre at the center of much of the current research into the age process. A count recently published in scientific discipline journal The Lancet links the lengths of telomeres with step of survival among tidy sum over 60, the first study to make this connection. What are Telomeres? To jockstrap understand the role telomeres do within the humans body, its utilitarian to review some radical biology. All of the tissues within the human body are do up of individual carrels. These prison cells comprise chromosomes within their nuclei. Chromosomes are the packages that realise most of our desoxyribonucleic acid - the familial instructions that declare the cell what to do. Telomeres are recuring desoxyri bonucleic 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 some as 20,000 base pairs of DNA. What do Telomeres do? Telomeres are pattern to serve a parallel of purposes within human cells. One, the telomeres figure out end caps for their chromosomes.
Without them, the body would need no way to receive where the chromosomes ended. It would treat them as befuddled pieces of DNA and would attempt to renovate them by joining them with separate chromos omes. With telomeres, the body can tell wher! e 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:
