Recombinant DNA Technology

DNA molecules from two distinct species are combined using recombinant DNA technology (rDNA). In order to create novel genetic combinations useful for science, agriculture, and industry, the recombined DNA molecules are injected into a host organism. A geneticist is responsible for isolating, describing, and modifying genes. DNA sequencing and cloning are the two other main technologies on which (rDNA) technology is based. The goal of cloning is to create copies of a specific gene or DNA sequence of interest. After cloning, the following step is to locate and isolate that clone from the other library members (a large collection of clones). The nucleotide sequence of the cloned DNA segments can be determined.
