The primer in DNA replication is?:-
A) Small ribonucleotide polymer
B) Helix destabilizing protein
C) Small deoxyribonucleotide polymer
D) Enzyme joining nucleotides of new strands
Dear Student
Ans. Option A is correct: Small ribonucleotide polymer.
RNA primers are short nucleotide sequences that are needed to initiate replication. During initiation, primers are added on both the separated strands of DNA leaving 3'OH free for the addition of new nucleotides (polymerisation) for elongation, to form two new strands of DNA.
