Function of primase
WebWhen DNA polymerase reaches a primer from prior DNA synthesis, the primer is removed and replaced with DNA. RNA primase lays down an RNA primer to start DNA replication. If a mutation occurs that blocks the function of RNA primase, which synthesis of which strand is affected, and why? Question 6 choices Choice A., WebWhat is the function of primase? a. synthesis of the short section of double-stranded DNA required by DNA polymerase b. synthesis of a short RNA, complementary to single-stranded DNA c. closing the gap at the 3′ end of DNA after excision repair d. removing primers and synthesizing a short section of DNA to replace them b
