Question

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

Answer 1

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 .

Answer 2

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.
