The Flow of Genetic Information

One base can rewrite life's blueprint — transcribe 9 DNA bases into mRNA base by base, translate 3 codons into a Met-Tyr peptide using the codon table, then swap a single base to compare silent, missense, and nonsense mutations.

About this app
The Flow of Genetic Information is an interactive high school biology lesson on how DNA information becomes protein. Step through transcription by pairing nine DNA template bases with complementary mRNA bases, then translate three codons using a codon table to produce a Met-Tyr peptide and stop at a stop codon. Finally, change one DNA base and compare silent, missense, and nonsense mutation outcomes.
