This video segment from the Secret of Life School Video: "On the Brink: Portraits of Modern Science" explores the genetics of breast cancer. [3:40]

Learn how genetic disorders are passed from parents to children as explained in this excerpt from Blazing a Genetic Trail, from the Howard Hughes Medical Institute.

In Blazing a Genetic Trail, by the Howard Hughes Medical Institute, follow this three-step approach to treating genetic diseases.

A collection of articles on evolutionary genetics focusing on the topics of phylogenetics, mutation and molecular population genetics, the genetics of speciation, genome evolution, and evolution and development. Learn how to read a...

Students will learn about the different types of mutations and how they work. They will compare the effect of these different types of mutations in DNA, including nucleotide substitution, nucleotide insertion, and nucleotide deletion....

Through informational text, interactive activities, practice problems, and video clips, students analyze how biological traits are passed on to successive generations.

This article gives information about childhood cancer and its most common cause, genetic mutation. Treatment information is also included.

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.

In this lesson, students learn how DNA fits into chromosomes, how chromosomes relate to the human body, DNA replication, and protein synthesis.

This lesson plan requires students to analyze DNA restriction maps to determine the differences in the sequence for several primates and humans. They then use the information to create a cladogram.

Within every cell in our body, two copies of a tumor suppressor gene called BRCA1 are tasked with regulating the speed at which cells divide. This learning module explains how these genes can sometimes mutate, making those cells less...

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.

Cell division is the only way single-celled organisms can reproduce. Learn more about cell division and explore the phases, checkpoints, and protein regulators of the cell cycle in this interactive. Find out how mutated versions of these...
