Acute lymphoblastic leukemia (ALL), a malignant disorder of lymphoid progenitor cells, is the most common hematological malignancy affects children, accounting for 25–30% of all childhood cancers with peak prevalence between the ages of 2 and 5 years [1]. The causes of pediatric acute leukemias are still not well known, the identification of causes and prevention/early intervention is clearly a worthwhile goal [2]. Previous studies have demonstrated that the interaction between genetic background

Introduction: Clubroot of Canola is a growing concern in Canada and in the U.S. (particularly in North Dakota). It is a potential problem for western Australia as well. Canola is a valuable crop seeds are primarily used to produce oil for consumption by humans although interest as biofuels, plastics, protein isolates, adhesives, and sealents is growing. Canola meal is also produced as livestock feed. (http://www.canolacouncil.org/markets-stats/industry-overview/)According to the Canola Council of

For this experiment, we were testing the effect of the growth hormone IAA on the rate of mitosis in onion roots. We hypothesized that if the growth hormone was added to the onion, the rate of mitosis would be faster than that of the control and our null hypothesis was that differences in numerical results are due to chance only . To test this, filled two cups with sand and put an onion plant in each, then added IAA solution to one cup and control solution (water and ethyl alcohol) in the other

Random Amplification of Polymorphic DNA (RAPD) Random amplified polymorphic DNA (RAPD) markers are analyzed by using PCR to amplify the segments of nuclear DNA. The use of a single primer (usually 8–10 bp long) that attaches to both strands of DNA and low annealing temperatures increases the likeli¬hood of amplifying multiple regions representing a particular locus (Welsh and McClelland, 1990). Although RAPD is a simple and inexpensive technique its major limitation is the inability to differentiate

Bloodsworth described the torments he faced while confined in the Maryland prison. Other inmates would yell through the pipes, “were going to get you Bloodsworth and do to you what you did to that little girl” (2013). He described being confined to a very small cell, while being kept locked away in isolation. He eventually went on to become the prison librarian. In prison he would keep up a healthy habit of reading. One day he came across a book that a guard had passed along. It was titled The Blooding

A DNA marker (size standard or a DNA ladder) is loaded into the first well of the gel. The fragments in the marker are of a known length so it can be used to help approximate the size of the fragments in the samples. The prepared DNA samples are then pipetted into the remaining wells of the gel. When this is done the lid is placed on the electrophoresis tank making sure that the orientation of the gel and positive and negative electrodes is correct. To separate the fragments, the electrical current

Figure 3. The measured distance migrated and calculated size of each DNA band from the experimental DNA sample treated with camptothecin and from a control which was not treated with camptothecin. The mean difference between the calculated size of the bands shows the size of the nucleosomal DNA on average with respect to the number of base pairs within one piece of linker DNA and connected to each histone. Results The relative band size of the DNA bands influences the distance that which it travels

Figure 2. A 1% LB Agarose Gel that was ran at 185 volts where lanes 1-8 were conducted by students and lane 9 is a standard to be compared to. This is an identical image as Figure 1, but instead here Lane 1 is being analyzed. Lane 1 contains a DNA substance that was labeled D3 and ran through the gel. Although the label D3 was known the true identity of the DNA substance is unknown. After measuring the distance migrated, we calculated the base pairs for each band by using the equation, log(# of bp)=

The results in this lab showed that suspect 2 was a match for the DNA found at the crime scene. This was determined by DNA fingerprinting. In this lab, the samples of DNA from two suspects and the DNA from the crime scene were cut with two different restriction enzymes and then the DNA was run through gel electrophoresis. The different restriction enzymes cut the DNA in different places, so when the DNA was run through the gel, the gel showed two fragments for each sample based on their size. The

The predicted antigenic regions were chimerically expressed in a bacterial system. Briefly, two sets of PCR primers were designed according to gD gene sequence available in GenBank (accession number: NC_001847) to amplify gene fragments encoding aa 20-160 (nucleotide 118953～119375, Δ gD1) and aa 257-344 (nucleotide 119664～119927, Δ gD2), respectively. The primers sequences for amplification of Δ gD1(P1 and P2) and Δ gD2 (P3 and P4) were listed in Table. 1. BoHV-1 genomic DNA was extracted using
