Codon Translation Lab

Interactive DNA → RNA → peptide learning model

Base Legend: A (Adenine) T (Thymine - DNA) U (Uracil - RNA) C (Cytosine) G (Guanine)
Synthetic teaching model • NCBI standard genetic code table 1 • calculations run in-browser • interface assets use CDNs
Phase: 1. DNA Double Helix

Synchronized Molecular Tracks

5' → 3' Direction
DNA Coding Strand (Sense) 5' → 3'
DNA Template Strand (Antisense) 3' → 5' (Complementary)
Transcription (RNA Polymerase)
mRNA Strand 5' → 3' (Uses Uracil 'U' instead of Thymine 'T')
Ribosome Grouping into Triplet Codons
Codons (Triplet Reading Frame 1) 3 Bases = 1 Codon
Translated Amino Acid Chain (Polypeptide) N-terminus → C-terminus

Step-by-Step Insight: Complementary Base Pairing

In the canonical Watson–Crick pairing modeled here, DNA A pairs with T and C pairs with G. During transcription, RNA polymerase reads the template strand 3'→5' while synthesizing RNA 5'→3'. The RNA transcript uses uracil (U) instead of thymine (T).
