Before it undergoes PCR the DNA extraction has a few steps to be done first, which is crucial to allow for amplification to begin, it needs to undergo cell lysis and denature the proteins, which then is purified (Tracey, 2017). The extracted DNA was then put into NaOH, a strong base and heated to 95 degrees Celsius, which leads to breaking down the hydrogen bonds between the nitrogenous (Tracey, 2017). Once all the previous steps have been completed, the PCR reaction can commence after mixing with primers, Taq DNA polymerase, reaction buffers and dNTPS. The Thermocycler was utilized to facilitate PCR making it faster, more reliable and cheaper (Tracey, 2017). The sample will undergo 35 amplification cycles, producing 3.44x1010 target sequences [ 235= 3.44x1010

There were several steps used to acquire the colony necessary for the PCR. First a student forearm was swabbed using a cotton swab, the cells were then placed in an agar plate. DNA was then extracted from the cultured bacteria by using a technique to lyse the cells and solubilize the DNA, then enzymes were used to remove contaminating proteins. The DNA extraction consisted of a lysis buffer that contained high concentrations of salt for denaturing. Binding with the use of ethanol and a washing step to purify the DNA. The final step for the DNA extraction was elution where the pure DNA was release. Proceeding the extraction of DNA the results of the 16s gene amplification were examined through gel electrophoresis it was analyzed by estimating the size of the PCR bands with marker bands. After measuring the success of the extraction, a technique called TA cloning was started. Cloning of PCR products was done by using partially purified amplified products with

The Basic Local Alignment Search Tool (BLAST) was the final portion of this lab report. BLAST is provided courtesy of the National Center for Biotechnology Information (NCBI). After running the five chosen tests, students were given the two 16S rRNA sequences that were associated with their assigned culture. The BLAST results served to confirm or disprove the hypothesis of what the unknown may be. The BLAST program compared the given 16S rRNA sequence to a database of known sequences and searched for similarity. (10) This search tool is capable of comparing nucleotide or protein sequences to find statistical significance between the matches. A perfect match to the unknown sequence is indicated by a

There are several body building routines that contain muscle building exercises. There are the common ones that most everyone has heard of and then some less common, but still effective mass building exercises. when planning your workouts you want to have a variety of these types of exercises incorporated into the program. This will help you get the most out of your workouts and build maximum mass.

Agarose gel was prepared to use for the detection of geneomic DNA by adding 1gm of agarose to 100 ml of 1X TBE buffer and it is dissolved by heating at boiling temperature. Then the agarose was left to cool at 55C°, before pouring in a casting plate to solidify. A required comb was placed near one edge of the gel, and the gel was left to cast. 1XTBE was poured into the gel tank and the gel plate was placed horizontally in an electrophoresis tank. The DNA samples were prepared by adding 1µl of loading buffer and mixed with 5µl DNA samples, and then the samples were added carefully to individual wells. Power was turned on at 45V for 15minute and 85V for 1 hours to run DNA or at 5-8v/cm. Agarose gels were stained with ethidium bromide by immersing

14 grams of the Alfalfa Pellet was measured using small trays and placed into a tray. This was repeated again using the same pellets and another tray. This would result in two of the four trays containing 14 grams of Alfalfa Pellets. The remaining two trays had 14 grams of Essentials (guinea pig) pellets placed into each of them. In all four trays the food was randomly dispersed. After all 4 trays were filled with the correct amount of food and sand, the trays were carried outside to the field next to the intersection of Taylor Street and Morgan Street. The two trays with the condition “cover” were placed near tall grass in the field. The tall grass represents “cover”. Finally, the remaining trays which had the “no cover” condition were placed out in the open. The trays were left in their spots for 24 hours. The next day all 4 trays were collected and brought back into room SES 3315 to be measured. A sieve was used to isolate the food from the

Polymerase Chain Reaction (PCR) is a laboratory technique commonly used to make many copies of a region of DNA. PCR has many research and practical applications and It is routinely

When utilizing PCR-RFLP, a DNA fragment is first amplified by PCR, then it is digested by a certain restriction endonuclease to generate a restriction polymorphic profile for the test subject species (Shaw et al., 2002). PCR amplification should be highly conserved among a species so that it can be easily amplified. Each fragment length is considered an allele, and RFLP occurs when the length of a detected fragment varies between individuals.

PCR was done in a final volume of 25 µL containing 5 µL of bisulfate modified DNA, 1 µL of each primer (1 µM), 12.5 µL of 2X Super Hot PCR Master Mix (Bioron, Germany) and 5.5 µL of H2O. PCR protocol was performed at 95 °C for 10 minutes, then 40 cycles at 95◦C for 30 seconds, annealing temperature for 30 seconds at 61°C for methylation and nonmethylation specific primers of MGMT and at 58°C for methylation-specific primers of ERCC1 or at 54°C for nonmethylation-specific primers of ERCC1, 72◦C for 30 seconds, and final

All the reaction components were thawed on ice. Working primer solution was prepared in order to make a final concentration in RT-qPCR reaction mix was 500 nM. For example, 5 µl of each forward and reverse primer sequence (stock concentration 50 µM) diluted with 90 µl nuclease-free water. Master mix was prepared on ice by adding 10 µl 2x iTaq universal SYBR Green supermix (antibody-mediated hot-start iTaq DNA polymerase, dNTPs, MgCl2, SYBR Green I dye, enhancers, stabilizers and blend of reference dyes), 2 µl of the working primer solution, and 4 µl nuclease-free water for a single reaction. Master mix was kept away from light and on the ice. 4 µl of diluted cDNA was thoroughly mixed and added to each well of 96-well qPCR plate. Master mix was thoroughly mixed and 16 µl of master mix was added to each well. qPCR plate was sealed properly and placed in a thermal cycler. Reaction protocol was set as follows: (1) Polymerase activation and DNA denaturation for 30 seconds at 95oC, and (2) denaturation for 5 seconds, followed by annealing/extension and the plate read for 30 seconds at 60oC. Total 40 cycles of step (2). The CFX Connect Real-Time PCR Detection System (Bio-Rad) was used for expression quantification. Gene expressions of preproglucagon, GPR40 and GPR41 were analyzed using above protocol and GAPDH was used as an endogenous control. Experiments were run in duplicates and repeated

At least 20 L. major kDNA haplotypes have been identified, by sequence alignment, in comparaison with sequences, presented in GenBank. Only 20 out of 80 (25%) PCR

Approximately 3.3 and 3.2 million clean sRNA reads were identified, respectively, from FGSC-9543 and CDC8219 strains, and 86.1% (FGSC-9543) and 69.1% (CDC-8219) of sRNAs were mapped to the genome. The median sequence length of the sRNA was 22 nucleotides (45.9- and 49.2% respectively for FGSC and CDC strains), with a minimum of 18 (1.6- and 0.92%) and a maximum of 30 (0.01- and 0.04%) nucleotides (Fig. 1). The sRNA reads were aligned to Rfam database {Nawrocki, 2014 #5988} to identify ribosomal RNA (rRNA), small cytoplasmic RNA (scRNA), small nucleolar RNA (snoRNA), and transfer RNA (tRNA) associated reads (Fig. 2A and 2B, 2C, and 2D).

From select prey colonies, plasmid DNA was isolated and sequenced at the Biocomplexity Institute of Virginia Tech using primers USD F2 (5’TGATCTTCAGCATCTTTTACTTTCACC3’) and USD R1

When doing the sequence alignment, using BLAST, the sequences were confirmed to be those of the eight species. In other words the sequecnes were confirmed to be from Homo sapiens sapiens (modern human), Homo sapiens neanderthalensis (Neanderthal), Pan troglodytes (chimpanzee), Pan paniscus (bonobo), Gorilla gorilla (gorilla), Pongo abelii (Sumatran orangutan), Pongo pygmaeus (Bornean orangutan), and Hylobates lar (gibbon). Using BLAST, we were also able to confirm that the species were closely related since similarities were 100% or 99% for mitochondrial 16s rRNA and 100%, 99% and 96% for the mtDNA control region.

We did not compare the modified assay with the previously published one; however, the modified assay performed well in detecting the circulating strains in this study. Furthermore, the rt RT-PCR were used for relative quantification to detect samples contain high genomic load (Ct ≤20) for further analysis. Consequently, all samples tested in this study by RT-PCR gave amplicons. Our results agreed with the previous reports showed a good correlation with different diagnostic assays in samples contain high genomic load (Soltan et al., 2015; Soltan et al., 2016).
