Transcription vs replication Transcription is chemically and enzymatically very similar to DNA replication
Transcription vs replication 6 Transcription is chemically and enzymatically very similar to DNA replication
Some important differencesi 1 RNA is made of ribonucleotides 2. RNA polymerase catalyzes the reaction, which does not require a primer(de novo synthesis) 3. The RNA product does not remain base-paired to the template DNA strand 4. Less accurate (error rate: 10-4)

5. Transcription selectively copies only certain parts of the genome and makes one to several hundred or even thousand copies of any given section of the genome(Replication?)
