They allow the chromosome to be replicated properly during cell division? Chronic sleep deprivation affects us on a cellular level. Not surprisingly, your telomeres like being well-rested just as much as you do—people who get roughly 7 or more hours of sleep a night tend to have longer telomeres, especially among the elderly. People who get five hours or less have much shorter telomeres.
These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle. And some researchers say it can live forever. In , Elizabeth isolated telomerase along with her student Carol.
Telomerase is an enzyme that is not only responsible in the synthesizing of new telomeres in the DNA, but also responsible for finding the length of the telomeres. She also investigated the effect of stress on telomeres and telomerase.
It was her recent discovery that mental and emotional stress may accelerate the aging process right from inside the cells. Elizabeth has been honored a number of times.
In , she was elected as a fellow of the American Academy of Arts and Sciences. In she became a fellow of the Royal Society of London.
In she became a fellow of the American Academy of Microbiology, and in a fellow of the American Association for the Advancement of science.
She later received her PhD from Cambridge University, England, where she also met her future husband. They have one son. Elizabeth Blackburn has taken an interest in the ethical implications of research and has contributed to the creation of a code regulating the field.
An organism's genes are stored within DNA molecules, which are found in chromosomes inside its cells' nuclei. When a cell divides, it is important that its chromosomes are copied in full, and that they are not damaged. At each end of a chromosome lies a "cap" or telomere, as it is known, which protects it. In , together with Jack Szostak, she further proved that this DNA prevents chromosomes from being broken down.
