Replication and transcription are two essential processes in molecular biology that deal with the synthesis of new nucleic acids. Here are the key differences between them:
- Purpose: Replication aims to produce a copy of the genetic information, conserving the entire genome for the next generation. Transcription, on the other hand, aims
Comparative Table: Replication vs Transcription
Here is a table comparing the differences between replication and transcription:
Feature | Replication | Transcription |
---|---|---|
Definition | DNA replication is the process of making two daughter strands, each containing half of the original DNA double helix. | Transcription is the process of synthesizing RNA using DNA as a template. |
Purpose | To conserve the entire genome for the next generation. | To make RNA copies of individual genes. |
Enzymes Required | DNA Helicase, DNA Polymerase. | RNA Polymerase, RNA Helicase (a type of DNA Helicase). |
Occurrence | Occurs in the S phase of the cell cycle. | Takes place in the G1 and G2 phases of the cell cycle. |
Product | Two daughter strands of DNA. | Single strand of RNA (mRNA, tRNA, rRNA, and non-coding RNA). |
Product Processing | Does not require processing. | Primary RNA transcript molecule needs processing to acquire final form and size. |
Degradation | Products do not degrade. | Products degrade. |
Replication is the process of duplicating the entire DNA molecule, while transcription is the process of creating a single RNA strand from a specific gene sequence. DNA replication is more accurate, as it creates a replica of the original DNA molecule, whereas transcription involves creating an RNA copy of a gene sequence, which may have some discrepancies.
