rna & evolution
« on: 18/10/2005 12:30:41 »
as the possibility of rna being the first genetic material
 is considered,is it possible that reverse transcriptase
was one of the earliest enz.which produced dna from the
existing rna?i dunno if this sounds crazy-as the enz.
 has no proof readin' mechanism,it would have caused more errors
which meant mutations & provided variations thus aidin' in
evolution[?]

arrrh but was RNA the first, some scientists believe PNA was the forerunner to rna and dna.

ok but what xactly is a psuedopeptide backbone?and what about the possible enz. involved in their formation??

thats sounds plausible to me, as mutations, while sometimes detrimental to the individual, provide the healthy variation in the growth of a species. If an organism maintained a strict control over its early genetic code, then it could be easily wiped out by a disease targeting a specific weakness underlying in all individuals of the same species
