James Bevan What is recombinant DNA and its advantages and disadvantages? In recent years science has been using recombinant DNA to genetically modify animals, plants and now technology has advanced to the point where there is constant speculation on manipulating human DNA. Recombinant DNA, or more commonly known as 'genetic engineering' involves "the combination of DNA from one organism with DNA from another organism". There are substances needed in bacterial cells. Firstly you will need the small spherical pieces of DNA named 'plasmids'. These are used as vectors, which simply means of transporting DNA into a cell. (1) "In molecular biology and genetic engineering a vector is a vehicle for transferring genetic material into a cell". Lastly you then need the required gene. There are numerous ways of extracting the gene, using DNA probes, or using mRNA. Restriction enzymes are then need to cut the DNA from its chain at specific...
