A recombinant DNA is artificially constructed DNA molecule with genes of interest that would not be present in the genome otherwise. It is a combination of a vector and a gene of interest. The recombinant DNA is inserted into bacteria E. coli, which, thanks to their reproductive potential, produce multiple copies of this recombinant DNA along with the chromosomal DNA.
