INTRODUCTION. A recombinant DNA molecule is produced by joining together two or more DNA segments usually originating from different organisms. More specifically a recombinant DNA molecule is a vector into which the desired DNA fragment has been inserted to enable its cloning in an appropriate host.This is achieved by using specific enzymes for cutting the DNA into suitable fragments and then for joining together the appropriate fragments.ore specifically a recombinant DNA molecule is a vector into which the desired DNA fragment has been inserted to enable its cloning in an appropriate host.
