Trace information from DNA to protein
See this course’s project requirements
A fictional plant inheritance notebook with DNA-to-protein explanations, simple inheritance crosses and a distinction between probability and certainty.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Label the fictional chromosomes, gene, alleles and trait.
- Trace the supplied DNA template through RNA and the codon key.
- Separate inherited information from supplied environmental effects.
- Build the two modeled inheritance crosses.
- Explain genotype versus phenotype probabilities and expected counts.
- Correct the nursery overclaims and include all changed cases.
Review and revise
Use these criteria to check your work and choose what to improve.
- Method: applies the course-specific rules to the supplied cases with visible intermediate work.
- Accuracy: results agree with the stated facts, units, boundaries and independent checks.
- Reasoning: explains why the result follows and identifies a limitation or unresolved question.
- Transfer: completes changed cases and revises the final project when a relevant assumption changes.

The idea in everyday life
Paper sequence only: DNA template 3-prime TACCGT 5-prime. Supplied RNA codon key: AUG=methionine, GCA=alanine, UUU=phenylalanine. Group RNA into three-letter codons. This two-codon model omits the full gene and stop signal; do not call it a complete functional protein.
During gene expression, transcription uses DNA information to make RNA; translation uses an RNA sequence at a ribosome to build an amino-acid chain. For this short model use DNA-template-to-RNA pairs T→A, A→U, C→G, G→C. Read the supplied DNA template left to right from 3-prime to 5-prime; the RNA is written 5-prime to 3-prime.

1. 1. Transcribe
Replace each supplied template base using the pair key.
You should see: RNA 5-prime AUGGCA 3-prime.
2. 2. Group
Split the RNA into three-base codons from the stated start.
You should see: AUG and GCA.
3. 3. Translate
Use the supplied codon key to name the amino acids.
You should see: Methionine then alanine.
4. 4. Explain
Distinguish copying information from building the chain.
You should see: Transcription produces RNA; translation reads RNA at a ribosome; the DNA does not become the amino acids.
What to finish
A labeled DNA-to-RNA-to-amino-acid information trace.
Watch for this
The exercise teaches information flow with two supplied codons. A complete biological protein requires additional sequence and cellular context.
How can I tell I understand it?
Transcribe a changed template and explain what each information-flow stage produces.
