A genetic mutation is an alteration in the genetic code found in DNA. A mutation changes the specific instructions of the gene, coded through small components of DNA. Because a genetic mutation ...

Radiation-induced mutation is unlikely to have induced genetic differences between dog populations in Chornobyl City and the nearby Chornobyl Nuclear Power Plant. Radiation-induced mutation is ...

For 30 years, researchers have known that Huntington's is caused by an inherited mutation in the Huntingtin (HTT) gene, but they didn't know how the mutation causes brain cell death.

The Huntington's mutation involves a stretch of DNA in the HTT gene in which a three-letter sequence of DNA, "CAG," is repeated at least 40 times, as opposed to the 15-35 repeats inherited by ...

Mutations represent biological mutation and are used to maintain genetic diversity from one generation of a population to the next by introducing random small changes. Selections are the stage at ...
