Question

Why do we need RNA primers in DNA replication?

Answer 1

RNA primers:

1. RNA primers are key to initiating DNA synthesis.
2. They provide the initiation sequence necessary for DNA polymerase to synthesize new strands.
3. The RNA primer is introduced at the template DNA site by primase enzyme on both the leading and lagging strands.
4. The 3'-OH free end of the primer is utilized by the polymerase enzyme to extend the growing strand.
