Transcription differs from DNA replication in the following aspects.
I. The type of enzymes involved
II. Length of DNA template involved
III. Number of DNA strands involved
IV. The site on DNA where the process is initiated
The differences between transcription and translation are
Transcription | DNA replication |
1. RNA polymerase is involved | 1.DNA polymerases, Ligase, helicase, topoisomerases are involved. |
2. Only transcriptional unit part of DNA is involved. | 2.Complete length of DNA is involved. |
3.Only one strand of DNA acts as template. | 3. Both the strands of DNA act as templates. |
4. Transcription is initiated at promoter. | 4. Initiated at Origin of replication. |
5. Has no repair mechanism | 5. Has repair mechanism |
