Genetic transformation occurs when a cell takes up (takes inside) and expresses a new piece of genetic material—DNA. You load the samples in a gel, connect the electrophoresis apparatus to the power supply, and turn on the power. Even a single base change can prevent a restriction enzyme from cutting a DNA strand. Remember that this particular mutation in the cystic fibrosis gene destroys a restriction enzyme site. Transformation, in biology, one of several processes by which genetic material in the form of “naked” deoxyribonucleic acid is transferred between microbial cells.Its discovery and elucidation constitutes one of the significant cornerstones of molecular genetics.The term also refers to the change in an animal cell invaded by a tumour-inducing virus.
