The genetic code is based upon the reading of how many bases at a time?

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.

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.
