Introduction

Recombinant DNA techniques and our society In this debate I will explain how recombinant DNA technology works its advantages and its disadvantages, I will then draw a conclusion from the evidence and knowledge that I have gathered. Deoxyribose nucleic acid or DNA has been modified through selective breeding, artificially since man started to breed plants and cattle. We can now take the DNA of one organism and place it into another, giving the new organism advantages for example resistance to herbicides or pesticides. This is done by very complex techniques. Firstly we need to find the gene that we will be coding for. We do this by using a probe, a shorter single stranded length of DNA; this carries the base pairing for the DNA that we are looking for. The probe is labelled with a fluorescent or radioactive marker. When the marker is added to the DNA under the correct conditions, the probe will attach to its complimentary DNA therefore showing where the needed DNA is. This can then be cut from the chromosomes using an enzyme called restriction endonucleases. There are a number of types of enzyme that do this, however each cut the DNA in a different place this is known as the recognition sequence. ...read more.

The advantages of Recombinant DNA are it provides an easy source of hormones, such as insulin. Before this technique had been developed, the insulin had to be removed from the kidneys of pigs. Today the insulin is produced on a large scale at minimal cost, which means more people can be treated. One advantage is seedless oranges; the seedless orange is a product of genetic engineering. It is one of the many marvels of this wonderful science it is an example of an instance where it has improved our lives in a frivolous and obviously harmless manner. Another advantage of this technique is the ability to produce food with out using animals this means these products are know consumed by vegetarians. Also it is a lot more precise than selective breeding because only the desired gene is replicated, where as before thousands of genes where randomly selected by nature. However the are main commercial reasons that there is advancing research into genetic engineering is, plants can be altered so they are immune to pesticides and increase the growth of the plants (speed and height) ...read more.

Conclusion

This explains my concern fully as a scientist I feel that this is a wonderfully attribute that our species has developed techniques to alter any other living organism on our planet. However with everything powerful someone or some company will try to take advantage and no amount of safe guards will stop this for example biological weapons. In conclusion I feel that this issue of GE is one far greater than I can decide upon. As a scientist I feel that this is the greatest break through of our generation. It will decrease the cost of food in both growing and purchasing. We can create vaccinations on large scales and therefore decreasing the price of the vaccination and making vaccinations more affordable to third world countries. We can now study gene mutating diseases, such as cancer and maybe one day cures these plagues. Despite this I also feel that there are moral issues that must be discussed first, and as a planet I feel that we are not ready or are responsible enough for this power to alter Mother Nature yet. We are still consumed with greed. Therefore if a company or a government has the power to change any living organism then it will use this power for its personal gain and not the advancement of our society. ...read more.

    'Discuss the advantages and disadvantages of the use of gene technology.'

    This extremely promising approach will require a lot of additional effort, but could change the lifes of millions of people. There are other practical uses of gene technology in other areas, one being crime fighting. Before genetic fingerprinting was developed, scientists had to rely on identifying certain proteins in blood

  1. The moral and ethical Issues of Recombinant DNA

    Eugenics is quite a big part of recombinant DNA. This is essentially where genes are inserted into humans (or their eggs or their sperm). This technique can be very useful in that it can prevent an early death (e.g. for people with SCID "Severe Combined Immunodeficiency").

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

    The height: width ratio of Limpets does increase with distance from the sea and my results support this conclusion. As a general trend the width of the Limpet shell will not exceed its height. Due to the rocky shore being sheltered, the height: width ratio increased which indicates that the shells are taller rather than wider.

    Some carbohydrates are relatively small molecules; the most important to us is glucose which has 6 carbon atoms. These simple sugars are called monosaccharides. The primary function of carbohydrates is for short-term energy storage (sugars are for Energy). A secondary function is intermediate-term energy storage (as in starch for plants and glycogen for animals).
