The Arguments For And Against The Uses Of Recombinant DNA Technology

Extracts from this document...

Introduction

The Arguments For And Against The Uses Of Recombinant DNA Technology Advances in genetics and molecular biology in the 1970s initiated the development and progress of recombinant DNA technology. Today, genetic engineering plays a very important role, not only in scientific research, but also in the diagnosis and treatment of disease. The objectives of recombinant DNA technology include identifying genes, isolating genes, modifying genes, and re-expressing genes in other hosts or organisms. These steps permit scientists and clinicians to identify new genes and the proteins they encode, to correct endogenous genetic defects, and to manufacture large quantities of specific gene products such as hormones, vaccines, and other biological agents of medical interest. The latest field of medicine to benefit from the advantages of recombinant DNA technology is reproductive endocrinology. Genetic engineering produces proteins that offer advantages over proteins isolated from other biological sources. These advantages may include: * High purity - this means that the bad genes will be filtered out so that the genes are efficient to do what they are required to do * High specific activity - This means that the recombinant DNA can be used to accurately specify in certain areas and the genes, which carry out certain tasks, can specify in certain areas. ...read more.

Many people all over the world suffer from a lack of sugar in their body. Bovine and porcine insulin was used which was very similar to human insulin but then it was realised that many people produced anti bodies against this insulin which neutralised its actions. Another factor was that people had to constantly inject them selves for the rest of their lives with this insulin to keep them alive. Then came research in to inserting the insulin gene into a suitable vector in the human. This would cause the E. coli bacteria cell, to produce an insulin which is chemically identical to its naturally produced counterpart. This is an example of how recombinant DNA can be used to help people who have medical problems. With this system the human is producing a protein inside of them which will provide them constantly with insulin meaning that they don't need to constantly take injections. This way is not only saving the person with this defect time but will also make them physically and mentally more confident as they will know that every thing they do that the insulin will still be being produced inside their body to keep the level of sugar inside them at a suitable level. ...read more.

Conclusion

People will have the power to change that they are in a genetic sense and nobody will be able to stop them. People will no longer be what they were supposed to be but just a genetically modified human being. Where could a limit be drawn to say only certain things can be done using recombinant DNA and can only be used by certain people. Although it is a wonderful solution to a lot of disease it is also a way of changing the human gene and as time goes on the main question will always be when do we stop. Maybe one day everybody will be a genetically modifies human being and their will no longer exist the human being as we know it today. At the end of the day someone must decide if this process is going to carry on and if the answer is yes how far until the line is drawn.

    MENTAL HEALTH

    4 star(s)

    Different myths and some true are as follows: - People with mental illness are violent and dangerous. As a group, mentally ill people are no more violent than any other group. In fact, they are far more likely to be the victims of violence than to be violent themselves.

  2. Investigate how the height to width ratio of Limpets varies with distance from sea

    There is no dramatic change in the beach profile; however, at this distance the beach became flatter and a large amount of Bladderwrack and Eggwrack was found to be covering the Limpets. My original method stated that I would work horizontally at the correct distance from the sea to obtain

    the modern human gene pool about four times earlier than the modern lineage began. Other studies have placed that date at around 125,000 years ago; the research published in Cell similarly estimates that Neanderthals and modern humans diverged about 550,000 to 690,000 years ago.

  2. Oncogenes are genes that cause cancer.

    If the virus carries an oncogene, the activity of the gene can convert the cell to cancerous growth. If the virus lacks an oncogene, the integration of the viral DNA can interfere with a cellular gene at or near the point of insertion; in other words, the insertion can cause a mutation in the host cell's genome.

  1. 'The use of recombinant DNA technology can only benefit humans'

    The spread of genetically modified plants would lead to greater survival rate and could cause the loss of wild plants. With the modifying of food it could cause humans who eat then to have allergic reactions to them. These crops could even be toxic to humans.

  2. patterns of growth and development

    The baby has to learn to balance and to how to co ordinate the muscles together. To development of the muscles in the legs and feet can happen when the baby kicks, which all babies enjoy doing. Here are the stages that happen to a child in developing how to use their legs.

  1. Investigation as to whether the aspect of a wall affects the growth of lichens

    as the northern and southern aspects of this wall are in such close proximity to each other. The only foreseeable difference that may occur on either side of the wall is amount of sunlight, which may result in a difference, however this is difficult to asses as there are so many variables when conduction such an experiment.

  2. Explain how DNA fingerprinting works.

    This is to establish what pattern of markers appears to be associated with the disease. Once the disease-associated pattern of markers is identified, it is possible to offer testing to relatives to determine who inherited this pattern, and therefore who may be at a higher risk of getting cancer for example.
