Biology Wise: Codon Chart
Explains the workings of the codon translation chart which provides the keys to the structure of amino acids. Includes a widget where one can input a nucleotide triplet combination and see which amino acid it represents. Includes RNA and...

Dna From the Beginning: Dna Words Are Three Letters Long
The genetic code is actually the three letter combination of bases that codes for an amino acid. This article describes the discovery of this code. Article includes animations, pictures, video, biographical information, and quiz...
Genome British Columbia
Genome British Columbia: Dna Code Bracelet
For this activity, students create a bracelet of beads using DNA code. Each letter represents an amino acid and is three beads. The authors suggest that even younger students would enjoy this activity, although older students will...
Khan Academy
Khan Academy: The Genetic Code
Learn how genetic code links groups of nucleotides in an mRNA to amino acids in a protein. Also learn about start codons, stop codons, and reading frame.

Serc: Building a Protein
This hands-on activity is an assessment of the students understanding of peptide and disulfide bonds formed during protein synthesis, and the structure of an amino acid (R-group plus the common structure that all amino acids share)....
