How do doctors fight a virus that's constantly mutating? Show science scholars how we fight HIV using one of its own most fundamental processes through a thoughtful demonstration. The lesson focuses on how protease inhibitors prevent HIV...

With AP Biology remaining the most popular AP science exam, many teachers need help preparing. The College Board offers the actual free-response questions from the 2017 test covering pollination, germination, and more. Scholars learn the...

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

This article contains information on how DNA is repaired to prevent mutated damage from interrupting DNA processes.

Experiments found that DNA could sometimes recover from damage. This article illustrates how the discovery was made. Article includes animations, pictures, video, biographical information, and quiz questions that are accessed by clicking...

[Free Registration/Login may be required to access all resource tools.] The process of DNA replication is not always 100% accurate. Sometimes the wrong base is inserted in the new strand of DNA. This wrong base could become permanent. A...

Try this quiz about DNA and evolution.

A webpage briefly explaining how a mutation in DNA and RNA can cause the wrong protein to be synthesized. Understand that DNA & RNA are long string of nucleotides that codes protein. The mutations shown include deletion, duplication,...

Mutations can cause a permanent change in the DNA of an organism. Over many generations, organisms have adapted through mutation which involves small changes between organisms which may allow that organism to compete better for survival....

Build a gene network. The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Explore the effects of mutations within the lac operon by adding or removing genes from the DNA.

This is a great lesson plan that combines Karoytypes and evolution. Students will recognize that the chromosomes of chimpanzees and humans are remarkably similar, then correlate that to their evolutionary relationship.

This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

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.
