The use of recombinant DNA technology can only benefit humans Recombinant DNA technology is the technology of preparing recombinant DNA in vitro by cutting up DNA molecules and splicing together fragments from more than one organism.(1) This is the process of using recombinant DNA technology to enable the rapid production of human protein from a single gene of insulin. Firstly the single gene required must be isolated. This can be done three ways: Either by working backwards from the protein- Finding the amino acid sequence for the protein needed, the order of bases can be established using known genetic code. New DNA can be made from this sequence of bases resulting in artificial gene made from complementary DNA. By using Messenger RNA- mRNA molecules carrying the code for insulin are common in the cytoplasm of insulin. Or using DNA probes to find the gene required-A probe is a short single strand...
