Why are there 3 bases per Codon ?

why are there 3 bases per codon; - it is energetically more efficient to have 3 bases per codon - is it by pure chance, two would work - four would not code enough (20) amino acids - two would not code enougth (20) amino acids

Answer:

None of those, but here's the answer your unimaginative teacher wants: - two would not code enougth...

Why will inserting a start codon into the beginning of a nonsense strand prevent a polypeptide from being made

In my bio paper.. 'Flavr Savr' tomotoes are tomatoes that have been genetically modified so that they take longer than normal to ripen. This delay has been achieved by disabling a critical tomatoe gene so that it fails to produce a protein that is needed...
