Question

The enzyme polynucleotide phosphorylase randomly assembles nucleotides into a polynucleotide polymer. you add polynucleotide phosphorylase to a solution containing the ndp nucleotides adenine and guanine. the resulting artificial mrna molecule would have ____ possible different codons if the code involved two-base sequences and ____ possible different codons if the code involved three-base sequences.

a. 2; 3
b. 2; 4
c. 4; 8
d. 4; 16
e. 16; 64

Answer 1

Answer;

C. 4; 8

Step-by-step explanation;

-Enzyme polynucleotide phosphorylase does not need a template; and, it could use as little as 1 NDP or as many as 4 NDPs as substrate. In fact, the sequence of the product RNA depended entirely on the number and concentration of substrate NDPs.

-The enzyme was subsequently determined that the enzyme’s function is to degrade RNA, not synthesize it; under test-tube conditions, however, it runs its natural reaction in reverse.
