Investigation: DNA, Proteins, and Mutations
Explore DNA mutations by transcribing and translating DNA code. Changes in the code result in point mutations, frameshift, and nonsense mutations.

DNA, Proteins, and Sickle Cell
In this activity, students use a codon chart to compare the DNA sequence of HbA (normal hemoglobin) to HbS (sickle cell). The DNA differs in a single base, where the codon for normal hemoglobin codes for glutamine, and the mutant form codes for valine.
