For a plasmid to be useful as a recombinant DNA vector, it must have some essential features. What
Title: Genetic pGLO Transformation Introduction: Genetic transformation is a transformation that involves a change in genes. Transformation is the process by which the genetic material carried by a cell is altered by the incorporation of foreign exogenous DNA into its genome. In this lab, we used a procedure called heat shock, accompanied by a bacterial plasmid vector, to transform bacteria with a gene that codes for GFP (Green Fluorescent Protein). A vector is an agent “employed to transfer the gene from one organism to another” (Lab manual).
In this step 109 of 10 kb cassettes were generated. All the cassettes that included errors were eliminated except for 19 polymorphic differences that were not important. Additional recombination provided 11 of 100 kb cassette assemblies. Since these assemblies were too large to be extracted from the E. coli, they were assembled in yeast. Exonuclease treatment and Ion Exchange Chromatography were some of the methods used to refine the DNA pulled out from the yeast.
Mankind has always been motivated by the desire for progress, accomplishment, and empowerment. The exceptionally steep rate of technological development during the twentieth century starting with the invention of the zeppelin in 1900 and advancing to the creation of more sophisticated technologies such as the world wide web is evidence of this truth. In the midst of all of these impressive innovations, biological scientists developed recombinant DNA techniques that gave them the power to alter genetic material. As biotechnology has become more refined and the application of genetic engineering in both agricultural and medical fields has become more common, the practice has fallen victim to harsh scientific and ethical scrutiny. The debate is
Retrieving this amount of data is both exhausting and time consuming. A short cut has been found that scientist use to analyze smaller segments of DNA. Short tandem repeats (STR) are segments of DNA sequences that are repeated. (BIO) The span of each STR differs from one person to the next.
As mentioned earlier, gene splicing was used to create them, fitting modern scientific processes
Vector is an organism that can carry the donor DNA into the host. The host organism is a multiplying microorganism such as a harmless bacterium, which serves as a factory where the recombined DNA can be duplicated in large quantities. The subsequently produced protein then can be removed from the host and used as a genetically engineered product in humans, other animals, plants, bacteria or viruses. The donor DNA can be introduced directly into an organism by techniques such as injection through the cell walls of plants or into the fertilized egg of an animal. This transferring of genes
Gene therapy has gained attention during the last 25 years as it offers great promise for curing genetic diseases, but there are also risks that come with the manipulation of the genes of an entire multicellular organism. The technology for genetic modification has been around since the 1970s, but today new research on a Cas9 protein may be the key to refine the process. The first simple, chimeric recombinant DNA (recDNA) experiment was completed by Cohen and Boyer in 1972 when they successfully inserted a mammalian rRNA gene into the pSC101 E coli plasmid. They used the endonuclease, or restriction enzyme, EcoRI to remove a specific gene from the DNA of an African clawed toad by severing the DNA at specific nucleotide sequences, called cleavage recognition sites. The DNA fragment was then added to a solution of E coli plasmids, which were also treated with EcoRI, and DNA ligase was added to form bonds between the mammalian fragments and bacterial plasmids, producing transgenic recDNA.

What is synthetic biology? What are the new ethical questions brought up by synthetic biology? Gathering voices that were mentioned in the 2009 publication “Ethics of synthetic biology” by The European Group on ethics in Science and New Technologies to the European Commission, it becomes clear that synthetic biology is based on the breakdown of properties of living organisms into building blocks that can be arranged and modified and combined to create or design a new (synthetic) organism to fulfill certain tasks 1. One of the differences compared to classical transgenic organisms, which are usually based on altered naturally occurring genes that are introduced to a genome of naturally occurring organism, is the fact that synthetic biology can be based on the introduction of synthetic units into synthetic cells that are based on minimalistic genomes.
Gene therapy can treat hundreds of typed of both genetic disorders and acquired diseases that may not have a cure or even and treatment. Some examples of gene therapy for genetic disorders can include, Severe Combined Immune Deficiency (ADA-SCID), Chronic Granulomatus Disorder (CGD), Hemophilia, congenital blindness, lysosomal storage disease, muscular dystrophy, etc. Some examples of gene therapy for acquired diseases can include, cancer, neurodegenerative diseases, viral infections (influenza, HIV, hepatitis), heart disease, diabetes, and hundreds of other diseases. For each of theses diseases, genetic or acquired, human gene therapy would be the treatment that can provide a cure for each and every one of them. This therapy, treatment, and revelation, is the future of medicine and the future to a longer, happier, and healthier human
Regenerative medicine has a treatment nowadays for our cells, organs and tissues repair and replacement normal function. Hence demands increase in population for organ transplantation. Research has conducted for recent and alternative therapies. Regenerative Medicine can medicate few cells that were damage due to agedness and congenital defects. In addition stem cell has a regenerative medicine; it regenerates, repairs, and restores functionality.
Genetic engineering mainly requires a particular gene to be transferred into a host cell using vectorbiomaterial that will facilitate the merging of the DNA with that of the host cell’s DNA. The aim of the process of genetic engineering is to produce useful or desirable characteristics in an organism. It includes; additions or deletions of targeted changes to a
Is Genetic engineering Safe? Genetic engineering is the modification of an organism’s genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. Human beings ought to consider the pros and cons of genetic engineering before using it. It is a contentious topic because people have different views of weather genetic engineering is safe or not.
