Question

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 artificial mRNA 3 nucleotide codons would be possible?

A) 3
B) 4
C) 8
D) 16
E) 64

Answer 1

The number of artificial mRNA 3 nucleotide codons that would be possible is eight (8), which are: AAA, AAG, AGA, GAA, AGG, GGA, GAG, and GGG.

Step-by-step explanation:

The arrangement of the nucleotides within the codon permit repetition. The adenosine triphosphate is designated as A, while the guanosine triphosphate as G. The possible number of codons that can be formed from this two available nucleotides is 2 to the power of 3 = 8

These codons are: AAA, AAG, AGA, GAA, AGG, GGA, GAG, and GGG.
