Answer:
5
Step-by-step explanation:
A codon is defined as a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule. Each letter represents a nucleotide: A- Adenine T- Thymine G- Guanine C- Cytosine. Looking at the strand of DNA, we can find 5 groups of three letters, or nucleotides, therefore there are 5 codons present.
