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…

DNA, Proteins, and Mutations
Students explore how DNA becomes a function protein by using a codon chart to transcribe and translate a gene. They compare the gene found in humans to that found in other animals, deducing that the genes are very similar with only slight changes. Finally, students examine the different types of mutations and how a…
