Transcription involves RNA synthesis from a template DNA strand, whereas DNA replication replicates the entire DNA double helix. DNA polymerase is essential for DNA replication, while RNA polymerase is key in transcription.
One difference between transcription and DNA replication is that transcription involves the synthesis of RNA from a template DNA strand, while DNA replication copies the entire DNA double helix to create an identical copy. In transcription, RNA polymerase catalyzes the formation of an RNA molecule using a single DNA strand as a template. On the other hand, DNA replication requires DNA polymerase to replicate both strands of the DNA double helix to produce two identical DNA molecules.
