Differentiate between transcription and DNA replication in terms of enzymes and processes involved.

Transcription and DNA replication are two essential processes in molecular biology that involve the use of DNA as a template, but they serve different functions and involve distinct enzymes and mechanisms.

1. Purpose and Outcome

• Transcription: The process of synthesizing RNA from a DNA template. It produces messenger RNA (mRNA), which is used for protein synthesis.
• DNA Replication: The process of copying the entire DNA molecule to ensure genetic continuity during cell division. It produces two identical DNA strands.

2. Enzymes Involved

• Transcription:

  • RNA Polymerase: The key enzyme that synthesizes RNA by adding ribonucleotides complementary to the DNA template.
  • Transcription Factors: Proteins that assist in the binding of RNA polymerase to the promoter region.
  • Helicase (in some cases): In _________ ____ ______ _______ ___ ________ ________ __________ _____.
