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

Explore the connection of genes and enzymes in regards to heredity and genetics. Concepts associated with dominant and recessive traits are also presented.

[Free Registration/Login may be required to access all resource tools.] Students will explore the factors that lead to evolution such as genetic mutation, gene drift and gene flow.

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

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.

Stem cells found in the bone marrow are crucial for our health because they are needed to become new blood cells that sustain and protect our bodies. But when the transformation goes wrong, harmful mutations can cause the cells to start...

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

[Free Registration/Login may be required to access all resource tools.] Describes three of the four forces of evolution: mutation, gene flow, and genetic drift.

Learn more about the operon model based on studies of lactose-dependent mutations of E. coli with the series of problems presented here. The correct answers have a brief explanation to reinforce the theories and incorrect answers are...

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.
