Re: The universal genetic code
This is a description of a modern cell with several billion years of evolutionary change behind it. However, there are various organisms today that are quite successful without having any dna. For example, virus are essentially self replicating rna strands (this isn't exactly accurate, but there structure is quite close to rna single strand formation, not the double helix form of dna.)
