The Benefits Of Genetic Engineering - 1001 Words

The article is based on the fact that microbes are capable of changing carbon dioxide into biomass. In most cases, the organism derives energy from sunlight, photoautotrophy and also from inorganic electronic donors, chemolithoautotrophy. It is by this that the authors claim that the potential for this organism to be used for the large-scale industrial production of biofuels and other useful chemicals remains largely untapped. The employment of genetic engineering to augment the autotrophic hosts productivity pathways offers hope for improved and increased productivity. Other techniques entail the transfer of the processes to heterotrophic organisms. Autotrophic production is said to be more efficient as a source of fuel than that from†¦show more content†¦This has given rise to microbial electrosynthesis where chemolithoautotrophs are used to generate chemicals and biofuels are generated from electron donors. Non-carbon electron donors include H2, Fe2+, NH4 and all are produced and mobilized by electrical energy. A suitable host physiologically, genetically and biochemically forms the basis for efficient autotrophic production. The heterotrophs Escherichia coli and Saccharomyces cerevisiae have so far been ideal. However, these organisms will have to be transformed to full autotrophs using sophisticated and complex engineering methods. The use of mixotrophy where autotrophs systems are incorporated into heterotrophs seems to give better outcomes. The natural photoautotrophic microorganism is categorized into oxygenic and anoxygenic groups. Oxygenic photoautotrophs such as Cyanobacterial Synechocystis species and Synechococcus species have been used in conjunction with metabolic engineering to produce isobutyraldehyde, l-lactic acid and 2,3-butanediol. Eukaryotic microalgae such as Chlamydomonas reimnhardtii can produce lipids and alkanes. Oxygenic photoautotrophs possess water splitting oxygen producing photosystems. These systems can produce reducing power and a proton gradient for ATP energy production. The photosystems of anoxygenic photolithoautotrophic microorganisms cannot split water. They rely on inorganic electronic donors to generate reducing power.

Genetic engineering is the genetic modification of an organism’s phenotype, also known as an organism’s genetic makeup. Genetic engineering can have its advantages and disadvantages, but I believe there are more advantages than disadvantages. There are a number of benefits that we can only discover if scientists consider to study andRead MoreBenefits Of Genetic Engineering1115 Words   |  5 Pageswill be talking about genetic engineering. What is genetic engineering? Genetic engineering is the process of directly manipulating an organism’s genes or DNA in order to change its characteristics. Over the years, genetic engineering and modification has been trialled on many different things, (CHANGE SLIDE) including food such as creating seedless grapes, CHANGE SLIDE and animals such as dolly the sheep, the first cloned animal in the world. However, genetic engineering, especially on humans hasRead MoreGenetic Engineering And Its Benefits1930 Words   |  8 Pagesprocess, genetic engineering provides more benefits that far outweigh the harms. Genetic engineering, and genetics in general, is a subject unfamiliar to the general public because not only has it not had much exposure to people outside of the scientific world, but it is also extremely complex and still has several applications yet to be found. In short, genetic engineering is the modification of an organism s characteristics or traits through manipulation, or replacement, of their genetic materialRead MoreBenefits Of Genetic Engineering909 Words   |  4 PagesResearch suggests that genetic engineering will be a vital tool in the fight against mosquito-borne diseases because current drug therapies are becoming less effective and genetic engineering approaches to mosquito management have shown promising results. c.

There are many aspects of genetic engineering and to thoroughly understand it looking into each is absolutely necessary. In order to understand genetic engineering, the key terms in this controversy that must be defined are the following: recombinant DNA technology, cloning, gene therapy, and the humane genome project. Genetic engineering is the alteration of genetic material by direct intervention in the genetic processes with the purpose of producing new substancesRead MoreThe Potential Benefits Of Genetic Engineering1721 Words   |  7 PagesGenetic engineering is a recent development that has gained tremendous commercial appeal. The potential benefits of genetic engineering have captivated the general public and clouded their moral values. The ultimate goal of genetic engineering is to create a utopian society where problems such as disease and world hunger no longer exist. Genetically engineering humans to be ideal beings may eventually lead to the creation of a â€Å"super race.† A super race is a race of strong, healthy, and highly intelligentRead MoreThe Benefits of Genetic Engineering Essay1108 Words   |  5 Pages The engineering of deoxyribonucleic acid (DNA) is entirely new, yet genetics, as a field of science, has fascinated mankind for over 2,000 years.
