Codon Protein Builder lets students type an mRNA sequence by clicking the bases A, U, G and C or pressing the keys. Each time three bases are entered, the ribosome reads the codon, a tRNA with the matching anticodon delivers an amino acid, and the protein chain grows. Translation begins at AUG for methionine and stops at UAA, UAG or UGA. Readouts show the last codon, the protein so far, its length and approximate mass. A random gene button, an Undo base button and a fast ribosome toggle help. It teaches translation and the genetic code.
Yes, completely free with no login. Any modern browser will run it, so it works on school tablets, whiteboards and personal phones.
There are 64 possible codons, since three bases each have four choices. They code for 20 amino acids plus a stop signal, so several codons can code for the same amino acid.
Translation starts at AUG, which codes for methionine. It ends at a stop codon, UAA, UAG or UGA, which do not code for any amino acid.
Click the base buttons A, U, G and C or press those keys. The Next codon readout shows what you have typed so far, and Undo base removes the last base.
