<prompt> If a 4 nucleotide sequence code for an amino acid instead of 3 then theoretically how many unique amino acids could be coded by such a system?1664128256  <response>: There are four types of nucleotides A, T, G, C.Normally the codons are made up of 3 nucleotides. Thus there are 43 64 possible codon combinations.If the codons are made up of 4 nucleotides, then there would be 44 256 possible codon combinations.If the codons are made up of 2 nucleotides, there would be 42 16 possible codon combinations.
