The Use Of Recombinant Dna For Science And Medicine

First, the human gene that codes for insulin production is isolated and then copied numerous times. Restriction enzymes are used to cut out a section of the plasmid DNA from E. coli bacteria. Then, the human insulin gene is inserted into the section of the E. coli plasmid that was cut out. These are then inserted into a viable host, where it will grow and multiply. The bacterial cell processes ‘turn on’ the human insulin gene allowing for it to be produced within that cell wall.

The first recombinant DNA created Herb Boyer and Stanley Cohen; they took a gene from African clawed toad Xenopus and put it into bacterial DNA. Gene splicing gained prominence in 1973 due to this event. The reason genetic recombination is possible is because DNA molecules from all organisms have the same chemical structure. In order to attain the desired molecule restriction enzymes are used to chemically cut the DNA. Boyer and Cohen’s success led to gene splicing being used to cure or eliminate diseases and create glowing bunny rabbits.

Genetic engineering is used in health treatments, agricultural applications, and environmental solutions. Genetic transformations incorporate foreign genetic material into the DNA of a different organism via a vector, which carries the genetic material. Plasmid DNA is small, round, and autonomous, due to its origin of replication. In biotechnology, plasmids carry beneficial genes, such as antibiotic resistance, and also a reporter protein, in this case, Green Fluorescent Protein

Lab Report on pGAL Transformation In order to understand this lab the student first needs to understand how recombinant DNA is formed. To begin, the student extracts a plasmid, which is a circular strand of DNA found within bacterial cells, from the bacteria. Restriction enzymes begin to cut the plasmid at certain sequences of nitrogenous bases.

We have technology everywhere in all aspects from organ transplants to digital and social media, the internet and cell phones and so much more. All of these technologies have helped us improve as a species and evolve at a rapid pace over the last few decades. We can quickly connect, get information and decide on which choices to make. More and more we realize the importance of personal health, healthy food, and the health of the planet. Technology in Genetics is moving front and center, gaining a higher profile than it has ever previously had. The GMO has brought about changes in resources for food and medicine and even animals. The controversy both for and against combined with mixed unclear information make it a bit of a double edge sword

Diabetes affects 9.3% of the population in America. It is the 7th leading cause of death in the United States [1]. Diabetes is a disease where the body is unable to produce insulin in sufficient amounts. The insulin breaks down glucose, so without the insulin, the glucose is unable to be broken down which leads to the buildup in the blood. Without glucose metabolizing, the body will not have energy to function [2]. Treatments for diabetes has varied throughout the years. However, the one thing they all have in common is insulin replacement. Previously, animal insulin was the only solution. Now, we are able to administer human insulin using a recombinant DNA technology [4]. It is most commonly administered with a subcutaneous injection.

Plasmids are small double stranded circular non chromosomal DNA molecules containing their own origin of replication. Hence, they are capable of replication independent of the chromosomal DNA in bacteria. Plasmids present in one or more copies per cell, can carry extra chromosomal DNA from one cell to another cell and serve as tools to clone and manipulate genes. Plasmids used exclusively for this purpose are known as vectors. The genes of interest can be inserted into these vector plasmids creating a recombinant plasmid. Recombinant plasmids can play a significant role in gene therapy, DNA vaccination, and drug delivery [Rapley, 2000].

Mutagenesis is the process in which specific changes are done to the DNA sequence to produce a specific gene product. In this experiment, Red Fluorescent Protein (RFP) is isolated and amplified through PCR as the gene of interest that will be inserted to a P1 plasmid that contains RBS (ribosomal binding site), promoter and antibiotic resistant gene. This will create a recombinant plasmid that will use the promoter and RBS from the P1 plasmid to express RFP. The created recombinant plasmid will then be cultured to produce bacterial colonies that will express the RFP reporter gene. One of the most significant processes used in this mutagenesis-driven project is the PCR amplification method.

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. This process has been taking place for much longer than scientists have been able to document. Those scientists are called geneticists and their field is genetics.

Objective: The purpose of today’s laboratory was to introduce a foreign gene into a cell using recombinant DNA technology by utilizing the techniques of DNA ligation and transformation of E.coli. Data was collected in the form of agar plates in order to analyze which colonies took up the vector alone and which colonies took up the

In recent decades, there have been many advances in technology, specifically in the field of genetic engineering, that allows precise control over changing the genes in an organism. Today, it is possible to incorporate new genes from one species into a completely unrelated species through genetic engineering. The

Genentech’s next major discovery was being able to clone human insulin with the help of other types of bacteria. From this information, some might think that there is nothing

The word science comes from the Latin word "to know" (Science Made Simple, 2014). In

Did you know that with the science of DNA manipulation, animal cadavers can be turned into insulin for diabetics? Back in the 80's scientists isolated the human gene for insulin and transferred it into bacteria. Now bacteria cultures are used to produce large amounts of human insulin. DNA manipulation is especially important in medicine, where it holds the hope of curing genetic diseases such as Huntington's, and even some types of cancer. There are several major types of DNA-manipulation enzymes used by living cells. The first type is DNA polymerase, which cells use to replicate their own DNA. The next type is DNA ligase, which joins 2 pieces of DNA to create a single piece. The third type is restriction enzymes, which appear to be made only by bacteria. Restriction enzymes are very important enzymes that are vital to our manipulation of DNA (Rapoza, DNA, 2).

    Through recombinant DNA techniques, scientists have already experimented with bacteria and copied their cellular system that allows them to defend themselves from viruses in order to create a new restriction enzyme called Cas9, which then gets bound to an RNA guide strand. This new enzyme introduces new genetic material into the human genome as DNA replicates. This method will be useful for families members who carry harmful recessive alleles. Their babies could inherit the genetic disorder, but with recombinant DNA techniques, the harmful gene or genes could easily be replaced with a functional gene. Lauren Friedman, Senior editor for
