Sorry, no etymologies found.
I wanted to ask about women in telomere research because it's been commented before that it's a field where, happily a large number of women have contributed.
And, we realized the old truism from the original cytogenetics which was that the telomere is really important for protecting ends and, as you might expect, the cell actually devotes all sorts of machinery to make sure that never goes wrong, or goes wrong as little as possible.
It serves as the template when the telomere is built, while the protein component is required for the construction work, i.e. the enzymatic activity.
A telomere is the cap of your DNA, and as you age or develop an illness it shortens.
With a blood test of white cells, they were able to measure damage to DNA, specifically the most fragile part of the chromosome, called the telomere.
Newswise — Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division.
A telomere is a region at the end of every cell chromosome that contains repeated DNA sequences but no genes; telomeres act to protect the ends of the chromosomes and prevent them from fusing together — rather like the plastic tips that keep shoelaces from unraveling.
If the cell cannot make a new telomere, which is the case in the maize gametophytes and the endosperm, trauma must be experienced as the evidence indicates.
A telomere is a region of repetitive DNA at the end of a chromosome, which protects the end of the chromosome from deterioration.
At the end of each chromosome is a marker called a telomere, which usually appears only on the ends.
