In the presence of an antibiotic, bacteria can be induced to take up plasmid DNA that carries a gene for resistance to the antibiotic. a. Transformation 3. There are three different mechanisms for genetic exchange between bacteria: conjugation, transformation and transduction. Students explore the biological process of bacterial transformation using E.coli and plasmid DNA. Transformation is the process by which foreign DNA is introduced into a cell. Then See page 3 for storage instructions. 16.7 Bacterial Transformation 1. Mutations. Impact of mutations on translation into amino acids. Transformation is the uptake of genetic material from the environment by bacterial cells. Before transformation, bacteria are treated with a chemical called calcium chloride, which causes water to enter into the cells and makes them swell. After transformation, the cells may express the acquired genetic information, which may serve as a source of genetic diversity and potentially provide … It was first reported in Streptococcus pneumoniae by Griffith in 1928.
