Because having each nucleotide code for only one
amino acid would allow for only four different
amino acids to be incorporated into a protein,
it was obvious to researchers that there had to be
a conversion between multiple bases and each
amino acid. Would two nucleotides at a time be
sufficient to provide enough codons to code for
all 20 amino acids? Why or why not? How many
amino acids could be coded for by codons
containing only two nucleotides? Will three
nucleotides per codon work? Why or why not?
Explain your answers.
If two nucleotides coded for each amino acid, the number of possible combinations would be 4x4, as each base could be ...
This solution gives a detailed explanation of why it is necessary to have a three nucleotide code in order to specify each amino acid in a protein.
