The enzyme polynucleotide phosphorylase randomly assembles nucleotides into a polynucleotide polymer. You add polynucleotide phosphorylase to a solution of adenosine triphosphate and guanosine triphosphate. How many different artificial mRNA 3 nucleotide codons could possibly be made?

Eight (8) different artificial mRNA 3 nucleotide codons possibly made.

Explanation:

According to above scenario, when we add polynucleotide phosphorylase into the solution of adenosine triphosphate and guanosine triphosphate there will be 8 different artificial mRNA containing 3 base sequence (codons) possibly be made while if code involves two base sequence there will be possibly 4 different codons.
