Transcription vs translation

Quick answer: Transcription builds RNA from DNA; translation builds polypeptides from mRNA.

These are sequential core steps for protein-coding gene expression.

Use the table rows first for rapid contrast, then read the similarity and difference sections to lock in exam-ready language. Finish with the “when to use which term” guidance before attempting the self-checks.

Diagram

DNA template RNA polymerase RNA transcript

Transcription copies genetic information from DNA into RNA, starting at a promoter and guided by base pairing.

In gene expression, transcription is the DNA → RNA step.

Side-by-side comparison

Feature Transcription Translation
Template DNA mRNA
Product RNA Polypeptide/protein
Machine RNA polymerase Ribosome
Location (euk.) Nucleus Cytoplasm / rough ER
Base pairing DNA–RNA complementarity Codon–anticodon (mRNA–tRNA)
Central dogma step DNA → RNA RNA → protein

Similarities

Both are essential for protein-coding expression.

Both rely on base-pairing rules.

Differences

Different templates, products, machines, and locations in eukaryotes.

Transcription precedes translation for a given message.

When each term applies

Use transcription when RNA is made.

Use translation when proteins are made from mRNA.

Common confusion

Do not say translation occurs on DNA in eukaryotes.

Common questions

Which comes first for a protein-coding gene?

Transcription.

Which uses ribosomes?

Translation.
