There are two essential substances found inside bacterial cells required before the process can begin. Present in the cytoplasm of a bacterial cell are a number of small circular pieces of DNA known as plasmids. Also present within the bacterial cell are restriction enzymes which cut DNA molecules at specific sites. By selecting the correct restriction enzyme, DNA molecules from different organisms can be cut at predictable sites to extract specific genes from lengths of DNAi. The first task in the process is to isolate the required gene. This can be done in three different ways; working backwards from the protein, using messenger RNA, or using DNA probes. Once the gene has been isolated, the next step is to cut the gene from its DNA chain. This is done...
