Case Study: Cystic Fibrosis Mutations
This case study is a follow-up to the Cystic Fibrosis Case Study where students explore how changes in transport proteins affects the movement of ions, resulting in a build-up of chloride ions and the symptoms of the disease. Students were introduced to the idea that different mutations can cause differences in the transport proteins, but…

Protein Synthesis Practice Using Codon Charts
Students practice using a codon wheel or codon chart to determine the amino acid sequence of DNA and RNA. Worksheet includes a short explanation of transcription, translation, and how amino acids are the building blocks of proteins. Students practice using the codon chart to determine which amino acids are indicated by the RNA code. They…

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.
