MCQ
In $\text{DNA}$ replication, the primer is:
  • A
    A small deoxyribonucleotide polymer.
  • A small ribonucleotide polymer.
  • C
    Helix destabilizing protein.
  • D
    Enzyme taking part in joining nucleotides of new strand.

Answer

Correct option: B.
A small ribonucleotide polymer.

$\text{DNA}$ replication is the process of producing two identical replicas from one original $\text{DNA}$ molecule. This biological process occurs in all living organisms and is the basis for biological inheritance.
Well, a primer is a short polynucleotide segment that primes, or prepares, the way for $\text{DNA}$ replication by helping $\text{DNA}$ polymerase to get started in doing its job. The primer is made out of $\text{RNA}$, so it's called an $\text{RNA}$ primer.
