Question

List FIVE similarities of DNA polymerases and RNA polymerases. List THREE differences.

Answer 1

Solution:
Difference between DNA and RNA polymerases

1) The enzyme which synthesizes DNA molecules from DNA nucleotides during DNA replication is known as DNA polymerase.On other hand,enzyme which synthesis RNA molecule from DNA during transcription is RNA polymerase.

2)DNA polymerases mainly used in the process of DNA replication.RNA polymerases used in the process of RNA replication.

3) DNA polymerases requires a primer for starting process of replication process but RNA polymerase do not require any primer.

4) Double stranded molecule is produced by DNA polymerase while single strand RNA molecule is produced by RNA polymerase.

Similarity between DNA and RNA polymerases

1) Both use DNA strand to produce DNA and RNA molecule.

2)Both add nucleotide in 5' to 3' direction.

3) Both have ability to form phosphodiester bond.

4)Base pairing rule is followed by both during polymer formation.

5) Source of energy is same for the enzymes.
