Question

Separate Eukaryotic DNA polymerases undertake Initiation and elongation

α polymerase synthesizes ___ comprised of a short RNA-DNA primer

Answer 1

Eukaryotic DNA polymerases, specifically RNA polymerase II, are responsible for both initiation and elongation during DNA replication. Initiation involves the synthesis of a short RNA-DNA primer by the enzyme primase.

Step-by-step explanation:

Eukaryotic DNA polymerases responsible for initiation and elongation perform distinct functions during DNA replication. The process starts with initiation, where RNA polymerase II, one of the three eukaryotic RNA polymerases, is involved in transcribing all the protein-coding genes. During initiation, a short RNA-DNA primer is synthesized by an enzyme called primase. This primer serves as a starting point for DNA synthesis.
