The Use Of Recombinant Dna For Science And Medicine

Introduction The use of recombinant DNA technology has been a huge advancement to science. In the early 1970s the first recombinant DNA was produced (â€Å"1972 First†, 2013). Researchers Stanley Cohen and Hebert Boyer used restriction enzymes to cut DNA at specific sites, and then fused them back together to form their recombinant vector (â€Å"1972 First†, 2013; Cederbaum, S., et al., 1984). Through transformation the vector is then inserted into a host cell to amplify their hybrid DNA, also known as recombinant DNA (â€Å"1972 First†, 2013). This technology allowed scientists to insert a human gene into the genetic material of common bacteria. This was a huge break through for science and medicine. Now the recombinant DNA could be used to produce protein encoded by the human gene (â€Å"1972 First†, 2013; Cederbaum, S., et al., 1984). The first protein to be synthesized from recombinant DNA technology was human insulin (Tuohy, P., 2013). To do this the human insulin gene was inserted into a plasmid, which had previously been cut by restriction enzymes. After the insulin sequence was added into the plasmid, the plasmid was then transformed into bacteria to amplify the insulin sequence (Tuohy, P., 2013). The new recombinant bacteria are then induced, and the bacteria produce more of the insulin. The insulin is then harvested and purified, so that it can be used to treat diabetes (Tuohy, P., 2013). Before insulin was produced through genetic engineering, it had to be obtained fromShow MoreRelatedThe Human Of Recombinant Bacteria1649 Words   |  7 PagesRecombinant bacteria is a bacterium cell that has had its genome changed, by the alteration, or edition of a gene. Recombinant DNA is DNA that has been artificially prepared by cutting DNA into smaller fragments and joining fragments together, that would not normally be found together naturally- even fragments taken from different organisms.( Principles of Gene Manipulation sixth edition, S.B.

Usually called biohacking, emphasizing the relationship with hacker culture, this form of public engagement in science has been the subject of controversy since its inception. The word hacking, usually associated with information technology, is a term used for the development of creative solutions for a problem by someone in aRead MoreRecent Uses of DNA Technology Essays1020 Words   |  5 PagesRecent Uses of DNA Technology DNA, Deoxyribonucleic Acid, is the basic structure for all life, it is the blueprint, the instruction manual, on how to build a living organism. DNA is made up of four nitrogen bases, adenine, thymine, cytosine, and guanine which are connected by sugar-phosphate bonds. Through a process called Protein Synthesis, the nitrogen bases are the code for the creation of amino acids. Essentially, DNA makes amino acids, amino acids make proteins, proteins make organisms.

Tremendous advancements in understanding the human genome trace back to Gregor Mendel’s cross breeding of pea plants, and have delved even deeper with the Human Genome project. While the research into recombinant DNA, introducing gene sequencing into originally created DNA strands in orders that would not occur naturally, has gone on for over thirty years, the societal disagreements and disdain towards the idea of cloning and other ‘morally corrupt’ forms of genetic alteration have raisedRead MoreThe Benefits of Ge netic Engineering Essay1459 Words   |  6 Pagescontroversy 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 substances or improving functions of existing organisms.

Abstract Genetic engineering is the technique of producing recombinant hybrid DNA by combining two different strands of DNA. The fundamental concept of genetic engineering is gene cloning; the technique of altering the genetic structure of an organism. Gene cloning has four basic processes, namely cutting : the process of isolating the required starnd of DNA, modification : the process of altering the ends of the strand so that they could be attached to anotherRead MoreThe Discovery, Process, And Applications Of Transgenic Bacteria1416 Words   |  6 PagesTransgenic bacteria, or genetically modified bacteria, is a type of recombinant DNA organism which uses bacteria as the host for inserting an exogenous gene.

We do not suffer any injurious effects from that defective genes as we carry two copies of DNA that carries two copies of the specific gene present in somatic cells. The gene which is likely to be harmful is recessive gene so if we inherit two copies of recessive gene from our parent, then disease will occur ( Carroll, 2011).Now days every year noticeable children are born with geneticRead MoreIs the Use of Transgeneric Organisms Essential to the Advancement of Therapeutic Medicine?1315 Words   |  6 Pages1.
