The type of RNA polymerase controlling DNA replication are
The correct option is D Only one type
DNA replication is the bidirectional, semiconservative process of synthesis of daughter DNA strand by polymerisation of deoxyribonuclotides using parental DNA strand as template. The process is carried out by DNA polymerase. DNA polymerase cannot synthesize daughter strand de novo but can only add monomers to already present DNA strand. This requirement is fulfilled by a primer which is a strand segment (complementary to the template). It has a free 3-hydroxyl group to which a nucleotide can be added. Most primers are oligonucleotides of RNA rather than DNA. A RNA polymerase, known as primase, synthesizes the primer using DNA strand as template. Thus, RNA polymerase with primase activity control DNA replication.
