What happens when genes change? Junior genetic investigators examine the effects of mutation in the third unit of a four-part Biotechnology series. Individuals discover the types of mutations through a series of PowerPoints, then partner...

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.] Covers gene regulation in eukaryotes.

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.

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...

[Free Registration/Login may be required to access all resource tools.] This article complete with labeled diagrams, key vocabulary terms, and review questions explains the connection between gene regulation and cancer.

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.

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,...

[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.

[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.

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....

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

Video discusses the concept of evolution and the five processes that can cause it to happen. [5:24] Includes a brief quiz and a list of additional resources to explore.

[Free Registration/Login may be required to access all resource tools.] An overview of cancer and its causes.

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

In this online mini-course learners distinguish between the structure, functions, and processes involved with DNA and RNA.
