Question

Choose the correct answers from the alternatives given :
The primer required to initiate synthesis of a new DNA strand consists of:

• A. An Okazaki fragment
• B. DNA
• C. A structural protein
• D. RNA

Answer 1

The correct option is D RNA

A primer is a short single strand sequence of RNA that serves as the starting point for DNA synthesis. This primer is usually of 18 to 22 bases. DNA polymerases then add the complementary bases to the existing DNA strand.

So, the correct option is 'RNA'.
