Question

DNA polymerase enzyme is required for the synthesis of

• A. RNA from DNA
• B. DNA from DNA
• C. RNA from RNA
• D. DNA from RNA

Answer 1

The correct option is B DNA from DNA

DNA polymerase enzyme helps in DNA dependent DNA synthesis by addition of deoxyribonucleotides, building blocks of DNA. This enzyme uses DNA as the template and synthesizes DNA. This process is also known as replication.

RNA from DNA is synthesized by RNA polymerase enzyme through the process called transcription. RNA is used as the template and nucleotides are for RNA synthesis.

DNA from RNA is synthesized by reverse transcriptase enzyme in some retroviruses where RNA acts as the genetic material.

So, the correct option is 'DNA from DNA'.
