Solution

The genetic code is a set of three different nucleotides taken at a time which code for a specific amino acid.
the code in unambiguous. Each codon specifies one amino acid only.
The code is degenerate. One amino acid may be coded by different codons
DNA sequence has three different reading frames determined whether you start at nucleotide one, two or three.
