Difference between DNA polymerase and RNA polymerase
Difference between DNA polymerase and RNA polymerase are in tabular form below –
No. |
DNA polymerase |
RNA polymerase |
Definition |
||
1. | An enzyme which helps in repair of DNA and responsible for DNA replication is known as DNA polymerase. | An enzyme which follows DNA strand during transcription process and synthesizes RNA is known as RNA polymerase. |
Exonuclease activity |
||
2. | In this enzyme, exonuclease activity takes place. | In this enzyme, exonuclease activity is absent. |
Synthesis |
||
3. | A double-stranded DNA molecule is synthesized by this enzyme. | A single-stranded RNA molecule is synthesized by this enzyme. |
Active phase |
||
4. | During S phase of interphase, this polymerase enzyme is active. | During G1 and phase of growth phase, this polymerase enzyme is active. |
Error rate |
||
5. | In this polymerase, error rate is low. | In this polymerase, error rate is high. |
Nucleotides |
||
6. | DNA nucleotides are used for the synthesis of strand. | RNA nucleotides are used for the synthesis of strand. |
