While the vast majority of eukaryotic organisms maintain their chromosome ends (telomeres) via telomerase, an enzyme system that generates short, tandem repeats on the ends of chromosomes, other ...
In whole animal cloning ( eg. Dolly ) the nucleus is taken from a somatic cell. So isn't shortening of telomeres a problem ?
The question "why do we age" has been asked numerous times. But why are we young? The cells of the adult human being are an age (time>0), but how can old cells create new cells that are younger than ...
I'm currently writing a piece of work about telomeres and aging, and wondered if you could share some good papers you've either read or know of.
Most animals age via at least two mechinisms: at a "macroscopic" level, basically wear and tear to the point where (on evolutionary time scales) it's more genetically advantageous to optimize for ...
