Question
Biology Question on Enzymes
The enzyme helpful in polymerizing RNA with defined sequences in a template-independent manner is:
A
Mononucleotide phosphorylase
B
Polynucleotide phosphorylase
C
RNA polymerase - I
D
DNA-dependent RNA polymerase
Answer
Polynucleotide phosphorylase
Explanation
Solution
Polynucleotide phosphorylase can synthesize RNA without a DNA template, which allows it to polymerize RNA in a template-independent manner. This characteristic distinguishes it from most other RNA polymerases, which generally require a template to function.
