BIC472 Student Name: Darshan Trivedi Partner’s Name: Manan Assignment 2 POLYMERASE CHAIN REACTION Total Marks: 12 1. (2 marks) In this experiment‚ you have amplified the D1S80 locus by PCR. Explain the advantages of using this locus to distinguish one person from another. Do you think you could use a coding gene for the same purpose? Clearly explain your answers. D1S80 locus is placed on the short arm of the chromosome 1. This locus

by using PCR. To begin‚ we had to prepare our 50.0 microliter of PCR composed of 2.5 microliter of DNA template‚ 37.0 microliter of water‚ 5.0 microliter of 10X Taq Polymerase Buffer‚ 4.0 microliter of 2.5M dNTP mix‚ 0.5 microliter of 20 mm Forward primer‚ 0.5 microliter of 20 microliter Reverse primer‚ and 0.5 microliter Taq Polymerase. All that was

achieved with 1 μl volume of whole blood and it was comparable to that of genomic DNA. No pretreatment of whole blood samples was required with the optimized buffer system. 3 mM concentration of MgCl2 was observed to be optimal and hence used in the reaction mixture. Amplification was relatively better with this buffer system as compared to that of commercially available PCR buffer. With the present technique‚ amplicon detection did not require the centrifugation/dilution of the PCR

The tissue samples were visualized using a Leica microscope (Leica Microsystems‚ Wetzlar‚ Germany)‚ and the Leica image manager software to enhance and photograph the sections. All sections were photographed and epidermal thickness was measured 50 places per section and the average epidermal thickness was calculated pr section (Fig. S5). The measurements were made on sections photographed at 10X enhancement. All sections were blinded to the observer during measurements. Strengths: Good method

from its biological source material using a hypotonic chemical buffer and being centrifuged. The extracted DNA is then measured to evaluate the quantity. After isolating the DNA‚ specific regions are copied with a technique known as the polymerase chain reaction‚ or PCR. PCR produces millions of copies for each DNA segment of interest and thus permits very minute amounts of DNA to be examined. The resulting PCR products are then separated. The separation methods used today include slab gel and capillary

wonders of science. The main idea or basis of the said film is that scientists were able to revive dinosaurs by obtaining their DNA out of the gut of ancient mosquitoes preserved in amber. The fragments of dinosaur DNA are augmented using PCR (polymerase chain reaction)‚ the gaps are filled in with frog DNA‚ and the repaired genome is then injected into an ostrich egg and brought to term in an artificial womb. The 1993 film Jurassic Park gave rise to various questions regarding science aspects‚ biosafety

conclusion is that laboratories performing cycling reactions (PCR‚ Cycle-sequencing‚ LCR‚ PCR) should validate their cycler at least twice a year‚ or every 100 runs. However‚ a more frequent validation is prefer able. The impact of sample block temperature in-uniformities and the lack of accuracy is not only proven by the used MTAS measurement sys tem‚ but also supported by biological evidence . Introduction Although the PCR process is a dynamic reaction‚ which takes place once the first denaturation

Title: Cloning of Enhancer of Zeste Homolog 2 in forward orientation into Escherichia Coli using histidine-tagged pbluescript II KS+. Abstract Enhancer of Zeste Homolog 2 locus is intensely over expressed in breast and prostate cancer and it’s been established that its promoter inhibition by p53 has led to reduced cell proliferation and invasion (Bracken‚ 2003; Xiao‚ 2011). Objective is to clone a forward orientated EZH2 insert into a his-tagged pbluescript. Cloning EZH2 into a histidine-tagged
