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

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.
