Mutation
In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from damage to DNA whic...

Resistance To HIV Drug Growing, Study Finds
HIV resistance to the antiretroviral drug tenofovir (Viread) is increasingly common, a new study finds. The researchers said their finding is surprising and alarming because the drug plays a major rol...
Grabbing A Parasite By The Tail: U-M Team Solves "Jumping Gene" Mystery
Deep within your DNA, a tiny parasite lurks, waiting to pounce from its perch and land in the middle of an unsuspecting healthy gene. If it succeeds, it can make you sick. Like a jungle cat, this para...
Video: Man Claims He Caught Three-Eyed Fish In Gowanus Canal
If the man in the video is to be believed, the first Gowanus Canal monster is your regular run-of-the-mill three-eyed fish. It was always only a matter of time until the putrid toxic waters of the Gow...
New Class Of DNA Repair Enzyme Discovered
A new class of DNA repair enzyme has been discovered which demonstrates that a much broader range of damage can be removed from the double helix in ways that biologists did not think were possible. Th...
Rare Mutation May Extend Survival In Lung Cancer Patients With Brain Metastases
Most patients with non-small cell lung cancer (NSCLC) that has metastasized to the brain have a dire prognosis. But Yale researchers have identified a subset of those patients with a rare genetic muta...
New Findings Shed Light On Fundamental Process Of DNA Repair
Inside the trillions of cells that make up the human body, things are rarely silent. Molecules are constantly being made, moved, and modified — and during these processes, mistakes are sometimes made....
Mutant Plant Munches TNT, Could Help Solve Cleanup Problems
A new study suggests that a mutant variety of a cabbage relative thrives on TNT, pointing the way to a potentially elegant solution for millions of acres of contaminated land. The plant, Arabidopsis t...
How Chronic Inflammation Can Lead To Cancer
Researchers discover how the immune system can create cancerous DNA mutations when fighting off infection. Chronic inflammation caused by disease or exposure to dangerous chemicals has long been linke...
Novel DNA Repair Mechanism Brings New Horizons
The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are neede...
Removal Of Ovaries Associated With Decrease In Breast Cancer Death In Women With Cancer, BRCA1 Mutation
Women who carry a germline mutation in either the BRCA1 or BRCA2 gene face a lifetime risk of breast cancer of up to 70 percent. Once they are diagnosed with breast cancer, they face high risks of bot...
Gene Therapy: 'Tame HIV' Used To Cure Disease
The lives of six boys with a deadly genetic disease have been transformed by a pioneering treatment to correct errors in their DNA, say doctors. A defective immune system in Wiskott-Aldrich syndrome l...

Mutagen
In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. ...
