Recоmbinаnt DNA technоlоgy involves combining DNA frаgments from two or more different sources to creаte a new genetic construct. The process typically begins with the use of restriction enzymes to cut DNA at specific sequences, creating fragments with compatible sticky ends. These fragments can then be joined using DNA ligase to form a recombinant molecule.One common application of this technology is the creation of recombinant plasmids for use in bacterial transformation. For example, a plasmid carrying antibiotic resistance genes may be cut with a restriction enzyme, and a gene of interest from another organism is inserted. The recombinant plasmid is then introduced into bacteria, which replicate the plasmid along with their own DNA. Bacteria that successfully take up the recombinant plasmid can be selected for based on their growth in the presence of an antibiotic.This technique has numerous applications, including the production of pharmaceuticals like insulin, improved crop traits in agriculture, and studies of gene expression. By enabling the targeted insertion of genes into specific vectors, recombinant DNA technology has revolutionized biotechnology.A researcher is attempting to create a recombinant DNA molecule that combines a plasmid with a gene coding for insulin. The plasmid includes a kanamycin resistance gene. After mixing the plasmid and the insulin gene fragment with restriction enzymes and ligase, the researcher grows the transformed bacteria on agar plates containing kanamycin. What is the purpose of growing the bacteria on kanamycin-containing plates?
