Matthew: I mentioned to Karen the other day how depressing it is that we've gone through a 1/4 of our lifespan already. It's weird to think about.
me: well my lifespan is 100+ years
Matthew: oh right i forgot. i'm 300+ so i guess i'm fine.
me: yeah, but seriously
Matthew: actually, scientists think that biological immortality is likely to be figured out before we die.
me: Probably, i know how too.
Matthew: yeah? how's that?
me: Its kindof cool actually. It has to do with DNA replication. You see, when DNA replicates, because of the way it replicates, there is an end-problem, which means that part of the DNA strand is lost everytime DNA replicates. This is obviously bad because we don't want to lose genetic information. So the way that nature got around this is by making something called Telomeres. Telomeres stick to the ends of DNA strands and are basically sacrifices; they don't contain any genetic information. So instead of losing genetic information during replication, a telomere is instead lost.
Well, apoptosis, which is cell death, is regulated by the protein that makes these Telomeres. If the telomeres get low, the cell kills itself to avoid replicating a bad cell. However, if the protein (telomerase, i think) continues to create these telomeres then theoretically, the cell will never die.
Unless something else happens to it of course.
Matthew: so... we just have to make sure they're can keep producing telomeres?
me: =immortality (tada!)
