The use of recombinant DNA technology can only benefit humans

Introduction

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 of DNA carrying the known genetic code we are looking for. So the location of the DNA probe is known, it is labelled with a radioactive fluorescent marker. ...read more.

Cells that have not taken up the DNA will be killed by the antibiotic. (3) Recombinant DNA technology has many different uses. It is used for genetically engineered micro organisms. This is when human genes are inserted into bacteria which are then grown in fermentors. The bacteria then produce a human protein. So, large amounts of insulin and human growth hormone can be produced cheaply. It is used to map human chromosomes (The human genome project). The aim of this is to create a map of all the human chromosomes identifying the precise location of every gene. This will help to develop a new gene therapy treatment It can be use for identification of mutations-people may be tested for the presence of mutated proteins that may be associated with breast cancer, retinoblastoma, and neurofibromatosis. It can be used for Diagnoses of affected and carrier states for hereditary diseases -Tests exist to determine if people are carriers of the cystic fibrosis gene, the Huntington's disease gene, the Tay-Sachs disease gene, or the Duchenne muscular dystrophy gene. ...read more.

Conclusion

In some cases this process could prevent early death. However, in others it could be used to give individuals characteristics that are considered to be desirable. This is unacceptable to many people. Objection to specific transgenic organisms- Many religious groups could not use products from specific organisms Finally screening could lead to discrimination against individuals-When fetuses are screened for genetic disorders, parents often face a dilemma about aborting affected fetuses. It will become possible to screen adults for genes that predispose them to genetic disorders. This might lead to insurance companies discriminating against people with these disorders, even though they have perfect health.(2) In conclusion recombinant DNA technology can help many people by stopping illness but this process has also been vandalised for many uses which are not necessary. For example it could be used to give individuals characteristics that are considered to be desirable. This reminds some people of some of the programmes that have been used throughout modern history to eradicate less powerful ethnic groups. Also this treatment may stop genetic disorders but this could lead to everybody being cured of illness. Therefore if people don't die of the genetic disorders the world would become over populated. 1. http://www.wordreference.com/definition/recombinant%5FDNA%5Ftechnology 2. http://www.follistim.com/Consumer/FollistimCartridgeBasics/RecombinantDNATechnology/index.asp?SetSession=Yes&strGUID={CE62B961-B16A-466A-8A45-5B0B166BB24D}&SID=294222698 3.
