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.
