DNA is the better genetic material than RNA. Justify the statement with three comparative reasons.

Answer»
  • DNA is more stable because even if the two complementary strands are separated by factors like heat, they can come together again. But RNA is more labile and easily degradable because of an additional – OH group in the 2 position of ribose in every nucleotide. 
  • DNA does not acy as enzyme. But some RNA molecules act as enzymes and therefore, are more reactive. 
  • DNA has Thymine which gives additional stability. RNA molecules do nit have thymine. 
  • Both RNA and DNA can mutate. But RNA mutates at a faster rate as it is less stable.
