Open in App
Solution
The correct option is C Ochcoa enzyme
The RNA polymerase is an enzyme that can synthesize the RNA in-vitro but it needs DNA template to do that. An enzyme called polynucleotide phosphorylase, also called Ochoa enzyme can synthesize template-independent RNA in-vitro. This enzyme uses ribonucleoside diphosphates instead of ribonucleoside triphosphates used by RNA polymerase. The same enzyme breaks down RNA in-vivo.A. RNA polymerase needs DNA template.B. Reverse transcriptase synthesizes DNA from the RNA template.C. Ochoa enzyme can make template-independent RNA in-vitro.D. DNA polymerase makes DNA from DNA template.Hence, the correct answer is 'Ochoa enzyme'
