Site directed mutagenesis

Background[ edit ] DNA may be modified, either naturally or artificially, by a number of physical, chemical and biological agents, resulting in mutations. Hermann Muller found that "High temperatures" have the ability to mutate genes in the early s, [2] and indemonstrated a causal link to mutation upon experimenting with an x-ray machine and noting phylogenetic changes when irradiating fruit flies with relatively high dose of X-rays.
