The Use of Recombinant DNA Technology Can Only Benefit Humans

Extracts from this document...

Introduction

The Use of Recombinant DNA Technology Can Only Benefit Humans I agree that recombinant DNA benefits humans only to a certain extent though. During the late 1960s and early 1970s a series of independent discoveries made in rapid succession yielded a new technology whereby humans have the capability to manipulate and direct the very evolution of life itself. This is accomplished through the process of gene splicing (Recombinant DNA). There are four essential elements of the process: a method of breaking and joining DNA molecules from different sources, a gene carrier that can replicate both itself and the foreign DNA, a means of introducing the foreign DNA into a functional bacteria cell, and a method of selecting from a large population the cells which carry the foreign DNA. Using procedures like recombinant DNA, many human genes have been cloned in E. coli or in yeast. ...read more.

People with failing kidneys can be kept alive by dialysis. But dialysis only cleanses the blood of wastes. Without a source of EPO, these patients suffer from anaemia. Now, thanks to recombinant DNA technology, recombinant human EPO is available to treat these patients, for treating anaemia, tissue plasminogen activator (TPA) for dissolving blood clots, angiostatin and endostatin for trials as anti-cancer drugs and parathyroid hormone. This shows that the use of recombinant DNA technology has benefited humans a lot over the past few years. A large Indiana-based pharmaceutical company developed a process for the production of human-type insulin through recombinant DNA technology. This insulin type, unlike that previously used, is biologically active and offers a great benefit to the diabetic. Many other biologists are also stepping up their production procedures for the manufacturing of products derived from gene splicing technology. ...read more.

Conclusion

But on the other hand it also benefits animals, not only humans. Livestock vaccines against diseases that attack the animals are also being produced, and they may be genetically engineering animals with less fat and more protein which better serve our nutritional needs. Recombinant DNA technology can be used to alter bacteria or small animals such as beetles or worms, so they destroy certain pests such as snails and slugs. But there are disadvantages of using this type o technology. By introducing a new predator into the ecosystem we deliberately alter its balance. Such an action may turn quiet harmful. The danger of this is if any particular organism does cause harmful knock on effects there will be problems removing it from the environment. This shows that the use of recombinant DNA technology does not ONLY benefit humans but benefits the whole environment and all the animals too. ...read more.

    wait and it repeat again, they are learning to communicate through sounds. The second stage is called First Words and happens at the age of 1-2 years. At 12 months a baby may use a few words by copying others; they can follow simple instructions and can understand simple everyday words like "sock".

    Crops could be more resistance to pests 3. Enhance resistance to bacterial, fungal or viral diseases 4. Improve resistance to herbicides, so that crop plants are unaffected by herbicides used to control weeds 5. Enable plants to resist cold or drought 6.

    The restriction enzymes SmaI cuts DNA vertically. This results in two DNA fragments with blunt ends. Next, the gene is spliced into a vector to make protein. A vector is a gene carrier which will carry a human gene into a bacterium. Plasmids are often used as vectors.

    The thing that makes the subject interesting, furthermore, is that human instinct also does not particularly like the idea of many people dying, when there may be a cure for their suffering. There are things that have already been proven by scientists to be possible in the subject of recombinant DNA technology.

    The fragments produced in this way can be joined using other enzymes known as ligases. "Also important in the manipulation of DNA are so-called vectors, which are pieces of NDA that can self-replicate independently of the DNA in the host cell in which they are grown."
