Difference Between Replication And Transcription

DNA replication is defined as the process involved in obtaining two daughter strands where each strand contains half of DNA double helix. This happens in the S phase of the cell cycle. The enzymes that take part in this process are DNA Polymerase, DNA Helicase. Transcription is a process of transferring the genetic information from DNA to RNA. This process is carried out in the G1 and G2 phase of the cell. It is catalyzed by RNA polymerase. To understand how they differ from each other, check out the differences given below.

Difference Between Replication And Transcription

Characteristics Replication Transcription
Occurs S phase of the cell cycle G1 and G2 phase of the cell cycle
Primer Requires RNA primer for replication to start Does not require a primer
Enzymes DNA Polymerase, DNA Helicase RNA polymerase, Transcriptase
Genome copy Entire genome is copied Only certain genes are copied
Position Found along the DNA strand Found only along 1 strand of DNA
Raw material dATP, dTTP, dCTP and dGTP ATP, GTP, CTP, and UTP
Intend Conserving genome for further generations Making copies of RNA of genes individually
Result 2 daughter strands mRNA, rRNA, non-coding RNA and tRNA
Degradation Products do not degrade Products degrade
