Bacteria also known as prokaryotes are very ancient single-celled organisms; fossils show that they were widespread 1.5 billion years ago. Today bacteria make up the vast majority of prokaryotes on earth due to the unfavorable ability to adapt quickly to the surrounding environment. Bacteria have the capabilities to survive in areas of high heat, extreme cold, or even very acidic or alkaline conditions. This ability is used frequently to fend off the effects of antibiotics and antibacterial;…

Purifying DNA to Estimate its Purity using PCR Amplification of VNTR to Load and Run Agarose Gel Introduction The study of this experiment was the Dopamine transporter gene. This gene is associated with different brain disorders like bipolar, as well as certain behavioural traits such as ADHD.[1] Dopamine transporter gene is a presynaptic plasma protein containing different VNTRs in it’s UTR and plays an important role in restricting the activity of dopamine by rapid reuptake into the…

Most amino acids are encoded by more than one codon. There are 64 total codons, three of which are stop codons, with 61 of the codons coding for 20 different amino acids. These codons, however, are not used equally. Codon Bias is defined as the deviation from equal usage of synonymous codons. Studies by Jan C. Biro found that the number of synonymous codons shows a significant correlation with the frequency of their respective amino acids. Furthermore, the redundancy of these codons may be…

the court-of-law, where you are sometimes expected to be at a case and testify. Q: What is the education requirement for this career? A: The education requirement is based off of a four year degree plan in Biology, Chemistry, Genetics, Molecular genetics, Molecular biology, Forensic science, Physics, Criminalistics, and Biochemistry. Few of the undergraduate degrees individuals may pursue for forensic DNA analyst careers include Bachelor of Science in Biology, DNA Analysis Methods, Bachelor of…

Restriction Mapping of Plasmid DNA Preparing 5 Eppendorf Tubes All tubes contain 1 μL of the plasmid DNA, and 2 μL of 10X buffer #2. Tube 1 is the control so there is no enzyme added only 17 μL DI water. For tube 2 the DNA is mixed with 0.5 μL of BamHI and 16.5 μL of DI water, to see total number of base pairs from the linear DNA. In tube 3 DNA is digested with 2 restriction enzymes, which can give the relative distance between the two enzymes. To be more specific, 0.5 μL of Bam HI and EcoRI…

The main goal of this study was to identify and analyze the D1S80 gene, and this experiment illustrated the versatility of these molecular biology techniques of PCR and gel electrophoresis to serve as methods identifying individuals. Both of the hypotheses made in this experiment that (1) there were genetic variation with the six students and (2) Student 3’s genotype was heterozygous were supported by the data. As seen in Figures 1 and 2 and Table 1 with different agarose gel percentages, it can…

Abraham Baraki 10/30/16 Bio-lab 4 report Angela Dipaolo Introduction Compare Diffusion and Osmosis Diffusion is the movement of substances from high concentration to low concentration. In this movement do not occur a membrane. Molecule of gas like perfume it can diffuse and sugar will be dissolve in the cup of coffee. In a diffusion process gradient concentration is high to low Osmosis is the movement of water through the permeable membrane. Osmosis is any the process of substance that…

One thousand- It seems to be a fairly large number, but in some cases, especially mine, it can be extremely small. The average person has from one hundred and fifty thousand to four hundred thousand blood platelets, yet there are times where I found myself with as low as one thousand of them. It was in times like those were I looked up to courageous people like Jackie Robinson, who faced difficulties head on with no fear. I quietly sat in the airport boarding gate with my eyes screwed shut,…

Quavian Belton Biochemistry I Dr.Nicholas Panasik October 6, 2015 PCR Optimization Abstract A Polymerase Chain Reaction (PCR) is a reaction that is set to catalyze the amplification of a copy of a piece of DNA. The aim of this lab was to optimize a PCR reaction by finding out the optimum concentration of MgCl2 needed. Six reactions were set up four with varying concentration MgCl2 and two primer control groups. The volumes and concentrations of each component of the PCR…
