A) promoter / DNA

D) ribosome-binding sequence / DNA

Question

Quizplus · Accepted Answer

DNA replication requires a primer to initiate the synthesis of a new DNA strand. In most cases, the primer is a short stretch of RNA that is complementary to a specific region on the DNA template strand. Once the RNA primer is in place, DNA polymerase can begin adding nucleotides to it and synthesizing a new DNA strand. Therefore, the correct choice is (C) primer/RNA.
