chromosomes. "Chapter 1: Hors-d'oeuvres and entrees/What is genetic modification? "The genomic rate of adaptive evolution". In this experiment, random mutations were introduced into the virus by site-directed mutagenesis, and the fitness of each mutant was compared with the ancestral type. Unifying Biology: The Evolutionary Synthesis and Evolutionary Biology. "Useful Mutants, Bred With Radiation".
"The molecular biology of cancer". Most of these so-called conventional plant breeding methods (such as gene transfer by pollination, mutation breeding, cell selection and induced polyploidy) have a substantially greater discard rate. In general, they are irreversible: Though exactly the same sequence might in theory be restored by an insertion, transposable elements able to revert a very short deletion (say 12 bases) in any location either are highly unlikely to exist or do not exist at all.

Prion mutations edit Prions are proteins and do not contain genetic material. Ion beam technology has been used in the discovery of new genes responsible for the creation of more robust plants, but its most prevalent use is commercially for producing new flower phenotypes, like striped chrysanthemums. "Repair of naturally occurring mismatches can induce mutations in flanking DNA". 49 Likewise, in yeast, Kunz. If it becomes necessary to differentiate between mutations in genomic DNA, mitochondrial DNA, and RNA, a simple convention is used. Imhof M, Schlotterer C (January 2001). Long M, Betrán E, Thornton K, Wang W (November 2003). 22 For example, more than a million copies of the Alu sequence are present in the human genome, and these sequences have now been recruited to perform functions such as regulating gene expression. Proceedings of an International Joint FAO/iaea Symposium. 96 Somatic mutations are not inherited because they do not affect the germline.
