Answer:
The correct answer is - option e. uses ATP as a substrate.
Explanation:
Poly-A Polymerase is an enzyme of the family of the DNA polymerase beta (polβ) family which catalyzes the reaction of the addition of AMP from ATP to the DNA polymerase beta (polβ) family.
ATP+RNA-3'OH--------->Pyrophosphate + RNApA-3'OH.
In this reaction, after the mRNA is cleaved, the Poly-A Polymerase template-independently adds about 200 A nucleotides (from ATP) one by one.
