[49] [50] There is a Web-based Analyser of the Length of Telomeres , software processing the TRF pictures. [51] A Real-Time PCR assay for telomere length involves determining the Telomere-to-Single Copy Gene (T/S) ratio, which is demonstrated to be proportional to the average telomere length in a cell. [52]
Telomerase, also called terminal transferase, [1] is a ribonucleoprotein that adds a species-dependent telomere repeat sequence to the 3' end of telomeres. A telomere is a region of repetitive sequences at each end of the chromosomes of most eukaryotes .
They then used α factor to block cells with induced short telomeres in late G1 phase and measured the change in telomere length when the cells were released under a variety of conditions. They found that when the cells were released and concurrently treated with nocodazole , a G2/M phase cell cycle inhibitor, telomere length increased for the ...
These are normally found only at the ends of a chromosome, but in chromosome 2 there are additional telomere sequences in the q13 band, far from either end of the chromosome. [ 13 ] We conclude that the locus cloned in cosmids c8.1 and c29B is the relic of an ancient telomere-telomere fusion and marks the point at which two ancestral ape ...

Telomeres protect your cells and DNA from damage. Artur Plawgo/Getty Images But when astronaut Scott Kelly spent a year in space, he came back with telomeres that were longer than when he left.

Telomeres are like protective caps of DNA at the end of our chromosomes. Longer telomeres are associated with longer lifespans, while shorter telomeres may potentially contribute to higher rates ...
