| The simple fact that there is a 1:1 correspondence between DNA nucleotides and RNA nucleotides and a 1:1 correspondence between tRNA and mRNA and a 1:1 correspondence between amino acids and tRNA... nope doesn't mean a thing.|
A small quibblette - only the first is a 1:1 correspondence. More than 1 tRNA can dock to the same mRNA codon due to 'wobble', and multiple tRNAs get charged by the same aaRS. Which are actually chemical reasons why Joe is wrong. The 'real' code isn't a neat reversible lookup matrix, like ASCII or something. If it were all 1:1, he might have a better point on 'information' - though it would still be chemistry.
hmm... cool... so there's all these different ways that mutations to the protein can happen, even if the DNA isn't mutated.
Thanks for the info!
