DNA technologies have revolutionalised modern science in many ways. DNA (Deoxyribonucleic acid), the hereditary material in all living organism from bacteria to animals and humans, controls and directs all the functions of a living organism. Many techniques have been evolved to understand and manipulate the DNA for many purposes like parentage analysis, curing genetic diseases, forensics, gene therapy and to improve livestock production.
Various different DNA based technologies are available for application in the production enterprises. With many more under development, it makes sense to be informed about the basic theory of DNA and the current applications available before making the decision to invest in DNA technologies.
