NAYAB SAJJAD BIOLOGY ESSAY SKILL I Recombinant DNA technology (genetic engineering) is a method of changing the inherited characteristics of an organism by altering its genetic material. Genetic engineering involves the manipulation of deoxyribonucleic acid, or DNA. Important tools in this process are so-called restriction enzymes that are produced by various species of bacteria.Restriction enzymes can recognize a particular sequence of the chain of chemical units, called nucleotide bases, which make up the DNA molecule and cut the DNA at that location. Fragments of DNA generated in this way can be joined using other enzymes called ligases. Restriction enzymes and ligases therefore allow the specific cutting and reassembling of portions of DNA. Also important in the manipulation of DNA are so-called vectors, which are pieces of DNA that can self-replicate (produce copies of themselves) independently of the DNA in the host cell in which they are grown. Examples of...
