Model boundaries

The displayed DNA is the coding strand written 5′ to 3′ for a short authored example.
Transcription and translation are simplified to emphasise information flow rather than enzyme-level detail.
Only the codons needed by the four reviewed sequences are modelled.

StudyVector-authored genetic-code model using fixed reviewed DNA sequences and deterministic codon translation; mapped to the curriculum topics shown below.

Accessible text description

A left-to-right pathway moves from a DNA double helix inside a nucleus to an mRNA strand, a ribosome with tRNA and a completed amino-acid chain. A manual timeline reveals five stages. The exact coding-DNA and mRNA codons are displayed, the changed second codon is highlighted, and the translated amino-acid sequence updates for four reviewed variants.
