immortal genes

Post by fandreea » Sat Nov 19, 2005 7:37 am

Regarding : Clones, genes and immortality - John Harris's book,
What do u think about the real immortality? Based on the fact that DNA replication is SEMIconservative, how old can be a piece of template DNA strand of ours ?
do we carry a piece of DNA from ancient people, our ancestors ?
Guess mainly mutations stay across.

Would like to hear your comments , thanks

Let's a assume we're looking at our ancestor's dna. It doubles before meiosis and then it splits into 4. Well two of the strands would be old and 2 would be new,if their offspring happens to be fertilized with the new strand(50% chance) and that was the only offspring, the old template would be lost and only the copy is carried on..
