Are some mutations more damaging than others? An engaging simulation encourages scholars to alter DNA through insertion, deletion, and substitution. It then forms resulting amino acids—or not—and the resulting protein—or not—depending on...

With paper DNA patterns, budding biologists model translation and base-pair substitution within sequences. Through these activities, they examine how mutations can result in genetic disorders. The modeling that occurs is an enlightening...

Tenth graders investigate the chemical composition of DNA and RNA and how they work together to synthesize protein. They discover genetic codes, gene chromosome theory, and how the environment influences our appearance.

Students determine the types of natural selection and variation that exists in a population, using beans.

In groups, learners read a case study of a couple who produced a child with hemophilia. Although tthe reading breifly mentions how a hemophiliac child is produced, the focus of this lesson is the ethical implications. This lesson is more...
