Deoxyribonucleic acid (DNA):
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, or a code, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules, most DNA is located in the cell nucleus.
DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel. Attached to each sugar is one of four types of molecules called bases. It is the sequence of these four bases along the backbone that encodes information.
DNA is used in various aspects in today’s technology, including genetic engineering, forensics, criminal investigation, historical and anthropological research, and DNA nano technology. Here we will emphasize on the use of DNA in genetic engineering.
Genetic Engineering refers to the modification or manipulation of a living organism's genes. It seems when most people think of Genetic Engineering it is in conjunction with the cloning of animals, humans, or other organisms. Genetic engineering, recombinant DNA technology, genetic modification/manipulation (GM) and gene splicing are terms that apply to the direct manipulation of an organism’s genes. Genetic engineering is different from traditional breeding, where the organism's genes are manipulated indirectly. Genetic engineering uses the...
