RNA translation worksheets

Codon decoding and polypeptide practice using the standard genetic code.

What these worksheets teach

Codon-by-codon translation using the standard genetic code, including start-to-stop ORF reading without inventing nonstandard codes.

Appropriate learners

Audience selectors include middle school, high school, AP Biology, and intro college. These labels guide difficulty and wording only — Chromatin.net does not claim verified accreditation or standards alignment.

Skills practiced

  • Read non-overlapping RNA codons
  • Apply the standard genetic code
  • Stop at the first stop codon
  • RNA codon translation — Translate RNA codons into amino acids with the standard genetic code.
  • DNA → protein — Transcribe then translate short ORFs into polypeptides.

How to use

  1. Choose a worksheet type, question count, level, and audience.
  2. Optionally set a seed to reproduce the same set later.
  3. Download the worksheet PDF and answer-key PDF, or open the print view.
  4. Generated links are private (noindex) and expire after cleanup. Permanent category pages like this one remain indexable.

Generate

Same seed + settings = identical questions and answer key (engine ws-1.0.0).

Example questions

  • Translate AUG…UAA and report the one-letter peptide.
  • Coding DNA → mRNA → peptide for a short ORF.

Teacher suggestions

  • Provide a codon chart unless you specifically want memorization practice.
  • Discuss that stop codons are not amino acids in the written peptide.
  • Assign the worksheet PDF first; release the answer key after class work.
  • Reuse a seed across periods for the same assessment version.
