Question

The enzyme polynucleotide phosphorylase randomly assembles nucleotides into a polynucleotide phosphorylase to a solution of adenosine triphosphate and guanosine triphosphate, how many types artificial $mRNA$ 3 nucleotide codons would be possible?

• A. $3$
• B. $4$
• C. $8$
• D. $16$

Answer 1

The correct option is C $8$

In the question, it is mentioned only adenosine and guanosine nucleotides are provided and from them 3 nucleotide codons have to be synthesized. So, the three sites of the codon can be occupied by either A or G. So, the possible combinations can give rise to 2 X 2 X 2 = 8 types of codons.

So, the correct option is '8'.
