WebTransformation in bacteria was first studied by a scientist Frederick Griffith in 1928. According to Griffith, the DNA or gene transfer can occur either naturally or artificially from one type of bacteria to another. For example, Transformation of non-virulent strain to a virulent cell or vice versa. WebOne example of a transgenic microorganism is the bacterial strain that produces human insulin. The insulin gene from humans was inserted into a plasmid. This recombinant …

WebIn this example, transformation efficiency is a number that represents the total number of bacterial cells that express the gene for ampicillin resistance divided by the amount of DNA plasmid used in the experiment. The transformation efficiency is calculated using the following formula. 1. Calculate the total number of transformed cells. WebThe first protocol for artificial transformation of E. coli was published by Mandel and Higa in 1970 [3]. The procedure showed increased permeability of the bacterial cells to DNA after treatment with calcium (Ca 2+) and …
