the genetic code is based upon reading 3 bases at a time
there are 4 nucleotides bases in DNA and 20 amino acids . In order to incorporate all the amino acids we consider 3 bases in genetic code 4 x 4 x 4 = 64
if we would take 2 bases - 4x4 = 16 that would leave out 4 amino acids without a code .
Three codons code for an amino acid . genetic code is set of relationships between codons and amino acid that code protein. It is three bases at a time read in the genetic code.
