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 is an enzyme that synthesizes DNA molecules from deoxynucleotides, the building blocks of DNA. It helps in DNA replication (DNA dependent DNA synthesis). This enzyme works in pairs to create two complementary DNA strands from a single original DNA molecule.

RNA from DNA (transcription) is synthesized by RNA polymerase.

DNA from RNA is synthesized by reverse transcriptase enzyme in some viruses.

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