Fragment

figuring out the radial fractures is looking at the initial fracture. Bullet fractures are round and has the same shape as a wheel. Fractures Also connects in the shape of a spider web. Then you have to figure out which side the fragment is facing in and which side of the fragment is facing out. Ridges called conchoidal fractures are created when a bullet hits glass, they are called conchoidal fractures. If multiple bullets fracture glass, it’s possible to figure out the order that they were…

Murder of Ralph Voosen On March 2nd at 1a.m., Officer J. Beach found a dead body lying on the ground. That person was identified as Ralph Voosen. He had a gunshot wound in his head and was surrounded by blood all over the floor. The time of death was estimated between 11p.m. and midnight on March 1. There was a note found in Mr. Voosen’s right pants pocket that read, “Meet me in your classroom at 11p.m. tonight. We need to talk.” I suspect that Brian Craig killed Mr. Voosen. I completed a…

one end of the gel. 3. What makes the DNA move across the gel?
By adding electrical current DNA moves. 4. Why do DNA fragments of different lengths travel to different locations on the gel? **Short fragments move through the wells in the gel more quickly. Over time shorter fragments in the sample will move further away from the starting point than the longer fragments. DNA fragments of the same length will move at the same speed and end up grouped together. 5. Why is the DNA stained? To make the…

A plasmid is circular, relatively small in size, double stranded as a DNA molecule, and is physically distinct from the chromosomal DNA of a cell. Innately found in prokaryotic bacterial cells, plasmids can sometimes be found in eukaryotes as well 1. Plasmids are self-replicating; therefore, when a plasmid is formed, infinite copies of the plasmid can be created if the plasmid is grown in bacteria. 2 Because of the size of plasmids, which can range anywhere from one thousand base pairs up to…

Upon completion of the PCR, the final product should be highly concentrated DNA corresponding to the gene of interest. We ran our gene of interest on gel electrophoresis to compare our gene of interest to a marker of known size to confirm the size of our genomic DNA. On the image of the gel (figure 1), the sample containing the DNA ran, but the sample containing the DNA ladder did not. As a result, an appropriate determination of the sizes cannot be made because there is no ladder to compare it…

The Sangers dideoxy sequencing method uses the dideoxynucleotide triphosphates (ddNTPs) as DNA chain terminators. For this method to work effectively, it requires the following: a DNA primer, a single –stranded DNA template, radioactively or fluorescently labelled nucleotides, a DNA polymerase, and modified nucleotides that play a role in terminating the DNA strand elongation. The DNA sample is divided into four separate sequencing reactions, containing the DNA polymerase and all four standard…

(5/6) and well 8 was negative control (7/8). The own sample was from Liu Ka Hin. Fragment size of PCR product was estimated about 421bp in well 6.…

protons and neutrons) that are currently present in the nucleus. This nucleus is likely to break up into two fragments due to its instability. These fragments are usually half its mass. After the fragments have been created is followed by emissions of a neutrons usually between 2 and 3 (normally 2.5). Nuclear energy works as all energy works on Einstein’s equation of E=Mc2 , the fragments that are released are usually 99.9% of the mass of the original atom. The mass deficit of 0.1% is converted…

Similarity indices and genetic distance The overall mean similarity index for Brassica oleracea accessions calculated based on all AFLP fragments amplified using Nei’s (1978) similarity index, ranged from 0.297 to 0.999 with an average of 0.744 (Table 3). The highest similarity indices (0.999) and the lowest genetic distance (0.001) were between the accessions of the same crop variety and geographical region, e.g. spring cabbage HRIGRU4564 and HRIGRU4571 from Cork. Accessions having close…

As a college student, there is nothing worse than getting an essay returned to from your professor with red markings labeling grammatical errors. As we learned, proofreading essays and reports helps us check for mistakes and correct them. One of the most common types of errors found is the “Run on Sentence.” This is often referred to as the grandfather of all mistakes (Miller & Whitehead, 2015).” Most people believe that it is impossible to write long sentences and be grammatically create.…
