Petite mutation



Template:DISPLAYTITLE:petite mutation petite (p-) is a mutant first discovered in the yeast Saccharomyces cerevisiae. The 'petite' yeast has little or no mitochondrial DNA, and forms small anaerobic colonies when grown on media. A neutral petite produces all wild type progeny when crossed with wild type.

Additional recommended knowledge

petite mutations can be induced using a variety of mutagens, including DNA intercalating agents, as well as chemicals that can interfere with DNA synthesis in growing cells.[1] Mutagens that create petites are implicated in increased rates of degenerative diseases and in the aging process.
