These class notes from a Microbiology course at Acadia University outline point mutations, frameshift mutations, mutagens, mutation rate, and mutant isolation. A good way to review already learned concepts.

Get a brief overview of the connection between mutations and genetic diseases. Several causes of mutations are also presented.

When life emerged on Earth about 4 billion years ago, the earliest microbes had a set of basic genes that succeeded in keeping them alive. In the age of humans and other large organisms, there are a lot more genes to go around. Where did...

A complete, student-paced lesson on genetics and inheritance. Students work their way through illustrations and animated tutorials, and answer review questions along the way. There is a self-checking quiz at the end of the lesson.

Find out what genetic mutations are and view some of the mutations that affect the wing structure, body color, eye color, and head shape of fruit flies.

Scientific information about the hereditary material in all living things, DNA. Also includes links to fact sheets for quick reference.

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.
