Forensic chemistry is the application of chemistry to provide information for use in courts of law or in public discussion and debate. It is a special branch of chemistry that is concerned with identifying the substances present in samples. A forensic chemist analyses predominantly biological samples such as blood, saliva, and semen (of which all contain DNA, proteins and amino acids) that are brought in from the crime scenes and reaches a conclusion based on tests run on that piece of evidence.…

Purpose Statement: The purpose of this experiment was to determine the Gram stain of the certain slant cultures we used in class, Escherichia coli and Staphylococcus aureus, under a microscope. Since it is the most important staining procedure in microbiology, it is used to distinguish between gram-positive and gram-negative organisms. The gram-positive cells stain purple, and the gram-negative stain a pinkish color. This staining is a differential stain that allows is used to identify the…

Bacillus anthracis is the causative organism of the serious infectious disease, called anthrax. There are three manifestations of this disease. The manifestations include gastrointestinal anthrax, inhalation anthrax, and cutaneous anthrax. This research will explore the morphology, virulence factors, reservoir, transmission, and portal of entry of B. anthracis. The pathogenesis will also be reviewed, including symptoms, how B. anthracis causes these symptoms, the possible complications of the…

broad categories of E. coli are separated into diarrheagenic E. coli and extraintestinal pathogenic E. coli, which includes uropathogenic E. coli.19 The sub-species grouping of E. coli (serotyping) are separated into an O (somatic), K (capsular polysaccharide), and H (flagellar) antigens which contain over 200 strains. The O antigen is part of the LPS layer and will initiate the inflammatory…

For example, if the minimum effective concentration needs to be ~10 '3 M for a drug with a molecular weight of -50 kDa, it becomes impractical. In regard to the candidate conjugated polymers, both natural and synthetic materials are used, e.g. polysaccharides, gelatin, amino acids, polyethyleneglycol (PEG), and numerous polyacrylates (Rock, and DeMichele, 2003). These…

water. The structure of amylose is helix with six glucose units. The glucose units or molecules are linked in linear fashion in amylose. However, the tetrahedral chemistry gives it spiral shape (Jenkins, et al., 1993). Amylopectin Almost 80% of polysaccharides taken up with diet are represented by amylopectin. It is formed by thousands of glucose units i.e. up to approximately 50,000 and is branched molecule. A lateral chain or branch point is present in approximately every 25-30 glucose units…

The focus of this lab was to identify an unknown organism based on its characteristics and the results from each of the tests. There will be various of test to choose from in order to identify the unknown organism, which will eliminate numerous possibilities and narrow it down to one. All the fundamental skills that we have learned and practiced in the lab will be used to perform on our unknown such as aseptic technique, microscopic examination, the use of differential media, and determining if…

salvia. Starch breakdown of amylase has received a great deal of attention because of their technological significance and economic benefits, and is also used for the commercial production of glucose. In storage tissues such as seeds, starch a polysaccharide of glucose is a hydrolyzing for utilization by the growing seedlings to meet its energy requirement. In storage tissues like seeds, the starch of a glucose is a hydrolyzing for utilization by the growing seedlings to meet its energy…

It is important to make an accurate diagnosis in this case as the risk of severe illness and treatment varies between an uncomplicated and a complicated UTI.1 The absent of classical presentation of loin pain and rigors would make acute pyelonephritis very unlikely. She was also haemodynamically stable on examination and showed no signs of urosepsis. Hence, based on this patient’s complaint of dysuria, frequency and suprapubic pain accompanied by urinalysis findings of leucocytes and nitrites;…

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…
