thats great thank you

yes but my question relates more to immortality like how do stem cells pass the hayflick limit where differentiated cells cant why is lengthening telomeres so much of a problem in humans when plants can do it why do cells like the hela cell able to pass the hayflick limit but lose control of cell reproduction essentially what is it about telomeres that humans can only live for about a hundred years while trees can live up to a thousand

yes 90% of cancer patients have active telomerase in the cancerous cells but trees use it constantly without this drawback how come they dont get cancer from it

Hi I would like to know about telomeres and immortality. How come humans have an increased chance of developing cancer when their telomeres are lengthened whereas trees can live several thousand years healthily. and what is the ALT path to reconstructing telomeres. can someone give me an answer or point me in the right direction. Thank you.
