Question

Which does not describe a function of the DNA polymerase molecule?

• A. Recognise the free nucleotide that pairs with the base on the template strand of DNA
• B. Read the strand of template DNA and recognise the base there
• C. Proofread to ensure that the proper base has been incorporated
• D. Make the proper nucleotide to match with the base read on the template strand

Answer 1

The correct option is D Make the proper nucleotide to match with the base read on the template strand

DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, the building blocks of DNA. The function of DNA polymerase is to replicate, proofread and repair DNA.DNA polymerases add nucleotide bases only when an RNA primer, a short piece of RNA, is already present.

So, the correct option is 'Make the proper nucleotide to match with the base read on the template strand'.
