Severo Ochoa synthesized RNA by polymerizing definite sequences, independent of a template, with the help of the enzyme ____.
Options:
Answer:
C
Solution:
Severo Ochoa discovered the enzyme polynucleotide phosphorylase, which is capable of synthesizing RNA by polymerizing ribonucleotides in a template-independent manner.
This enzyme was instrumental in the synthesis of artificial RNA molecules with defined sequences, which played a crucial role in deciphering the genetic code.
DNA polymerase and RNA polymerase require a template for the synthesis of nucleic acids, while restriction endonucleases are enzymes that cleave DNA at specific recognition sites.
Answer: Polynucleotide phosphorylase
