[Free Registration/Login may be required to access all resource tools.] Effects of mutations can be beneficial or they can be harmful. This tutorial describes the effects and provides examples of each.

This tutorial reviews how uncontrolled cell growth caused by mutations in the cell cycle may cause cancer.

[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...

This lesson will describe what a mutation is and how it can effect the outcome of protein synthesis. It is 3 of 4 in the series titled "Mutations."

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,...

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...

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.

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...

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...

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...
