Re: DNA

no chaps .i think u haven't gone in detai about cell dicision or in brief cell cycle.when we go to cell cycle ,it contains interphase and m-phase.in interphase [s-phase]dna replicates so the no of dna becomes double.but these replicated and old dna [formed by semi-consevative model of watson and cr...

thanks , this information is really new for me, i have studied that that DNA is natively present in water, and there is some hydrophobic interactions also involved in stability, do you have any idea about it?
