Answer:
The correct answer is option b.
Explanation:
Primase refers to an enzyme that plays an important role in DNA replication, the primers works as the point of initiation for the synthesis of DNA. The primase is a kind of RNA polymerase as it is an enzyme that give rise to short sequences of RNA known as primers.
Primase after getting associated with a single-stranded DNA template starts the process of the production of RNA. Primase combines with the DNA helicase and gives rise to a complex composition known as primosome. After binding with DNA helicase, primase gets stimulate and begins the production of the short RNA primer. Primase does not require a base-paired primer to start the process of RNA synthesis, however, it gives rise to sequences of RNA, which are approximately 5 base pairs in length.
