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.

    This allows scientists to produce new combinations of genes that may not exist in nature. For example, a human gene can be inserted into a bacterium or a bacterial gene into a plant. So far, however, there are limits to this ability.

    A group of three bases (codon) codes for a specific amino acid.

A polypeptide is formed as each amino acid is added from tRNA to a chain following the sequence on mRNA.

    The molecules being targeted are <1 nanometre in size, and so, by the sheer scale of the process, all the research becomes more complicated and therefore much more expensive. This would suggest that for finance reasons, only humans could benefit from recombinant DNA technology.

  1. Explain how DNA fingerprinting works.

    know approximately where it lies on a particular chromosome, indirect DNA studies may be used. Indirect DNA studies are also used at times when the gene identified is too large for analyses. Indirect DNA studies involve using markers (markers are DNA sequences located close to or even within the gene of interest)

    This means that genes are in pairs. For example, you have two genes controlling eye colour. Different forms of the same gene are called alleles. The gene for eye colour has different forms, such as the allele for blue eye colour and the allele for brown eye colour.
