The elucidation of the structure, function and metabolism of Deoxyribonucleic acid (DNA) has led to the current global revolution in the recombinant DNA technology, with the possibility to modify these molecules in many ways for the benefit of man and animals. In this review, we considered the basic principles of genetic engineering (gene cloning), bioinformatics, and its applications in medical and veterinary sciences. The issue of ethical questions and fears about biotechnology is also discussed. The ultimate goal of this paper is to re-invigorate the interest of medical and veterinary personnels, biochemists and related scientists to this technology, which is well able to have an effect on the way all the biosciences will be practiced in this new millennium.
