Molecular beam epitaxy

Imagine the potential of copying the DNA of a creature exactly, to create a replica of that creature. Opening a door to a multitude of scientific research. Now imagine the repercussions that could come from tampering with the natural cycle of life. Both seem intimidating, intriguing, yet convoluted. Since the first successful cloning experiment in 1996, a sheep named Dolly, there was is question that cloning is a force to be reckoned with. The experiment posed new opportunities and also…

Protein Purification Practical Report Student Name : Noel Murphy Date : 28 February 2015 UF/DF Practical Question Report Ultrafiltration (UF) and Diafiltration (DF) steps are carried out prior to every chromatography step and post the final polishing chromatography step. These UF and DF steps are vitally important, the UF step concentrates the protein product into a smaller volume of buffer, while the DF step alters the conditions the protein product is sitting in i.e. Buffer exchange.…

Q1. Explain segmental trans-splicing (STS) and mention a long gene 8 kb or more, this strategy could be used for. A1. Segmental trans-splicing concept is similar to that of trans-splicing, where exons of two different gene fragments are joined together. However, in STS it can be used to target gene sequences that are too large for a viral vector genetic capacity; for example the von Willbrand factor gene (8.6 kb) or the muscular dystrophy gene (11.0 kb). In STS a 5’exon of the gene is delivered…

A. Polymerase chain reaction (PCR) Principle It includes the primer mediated enzymatic amplification of DNA. It uses the ability of DNA polymerase to manufacture new strand of DNA complementary to the offered template strand. DNA polymerase can add a nucleotide only onto a preexisting 3′-OH group to add the first nucleotide that is way Primer is required. Then DNA polymerase elongates its three ends by adding more nucleotides to generate an extended region of double-stranded DNA.…

Recombination and mutation are the motivation of evolution. Recombination is critical for repairing DNA lesions and for chromosomal pairing, and exchange during meiosis (Krejci et al. 2012). Recombination does not occur uniformly on the chromosomes of eukaryotes. Meiotic recombination in well studied yeast revealed that non-uniformity of recombination was observed when the frame of reference is an entire chromosome, multigene region and a pair of genes or a small region upstream of a gene…

Transformation is the process by which competent bacteria take up genetic material (in the form of naked DNA) from the environment. In this lab, the process of transformation was conducted by using a plasmid containing various genes called pGLO along with the bacterium Escherichia coli. In order for transformation to occur in Escherichia coli, repeated washes in the presence of CaCl₂ followed by heat shock treatment (42°C for 50 seconds) occurred to induce the competence of the bacterium.…

To start this experiment, two microcentrifuge tubes were exposed to different ingredients. One was labeled “+DNA,” the other with “-DNA.” They were both filled with different bacteria. More specifically, the “+DNA” tube had pGFP in it and included a plasmid. Included on that plasmid were two genes: gfp (gene for green fluorescent protein) and an ampicillin resistant gene. The gfp gene makes cells glow and the resistant gene fights against ampicillin, which kills cells. This plasmid DNA was…

What is cloning? Coning is the process of making a replica of something using its DNA. How does it affect agriculture? One way cloning affects agriculture is animals. The perfect animal can be made through cloning. Take a farm animal for example. You take the DNA from one farm animal, and clone it. A cow for example, it would never be sick, if it was a milking cow, it would produce some of the best milk. If it was a meat cow, you would get the best beef. If a female, it would get pregnant with…

Paul Berg’s method for inserting foreign genetic information into DNA of SV40 was truly a paradigm shift. No longer was the study of molecular biology purely observational, Dr. Berg’s discovery gave scientist the traction to synthetically modify and transduce foreign DNA into a desired host. Because of this, not much was known about this type of genomic modification. Except for the knowledge…
