Hi all,
​
Quick question. I can't think my way out of this, but I'm sure an answer exists. As we get older, that is, more cell divisions take place, our chromosomes get shorter. Why is it that poor ol' Dolly, now sadly deceased, had telomere lengths consistent with the sheep she was cloned from. Yet during meiosis, the telomere length is "reset" for a newborn?
​
How can I reset my telomere length, I've checked the manual, but, no joy? It can't be that hard, surely?
​
Thanks,
​
Mark

Thanks for the replies.
So, if I'm understanding properly, telomerase is at work in the meiocytes tyat produce the gametes, & "restores" the chromosome length?
