Abstract Over the past twenty years, DNA analysis has been revolutionalized forensic science and has become a dominant tool in law enforcement. The DNA is unique for each and every person. This application is used in forensic science to identify the criminals. The DNA is isolated from the biological samples collected from the crime scene. […]
Analysis of Variations in Conserved Motifs of Cag A protein in Different Helicobacter Pylori Strains
Abstract Infection with strains of Helicobacter pylori that carry the cytotoxin-associated antigen a (cagA) gene is associated with gastric carcinoma. Recent studies have shed light on the mechanism through which the cagA gene product, CagA, elicits pathophysiological actions. Helicobacter pylori infection has an association with histological gastritis, gastric atrophy, gastric cancer, and mucosa-associated lymphoid tissue […]
Abstract DNA fingerprinting also called DNA Typing in genetics is the method of isolating and making images of sequences of DNA (deoxyribonucleic acid). The technique was developed in 1984 by the British geneticist Alec Jeffrey’s, after he noticed the existence of certain sequences of DNA (called mini satellites) that do not contribute to the function […]
Abstract DNA evidence is being increasingly used in court cases. The first DNA typing methodology used forensically required comparatively large amounts of starting material. Now, with the use of the polymerase chain reaction (PCR) to amplify Short Tandem Repeat (STR) segments of DNA, laboratories are able to analyze DNA from samples as small as a […]
Abstract Penicillin is one of the well known antibiotics that are produced by Penicillium species of Fungi. Due to the immense applicability of penicillin antibiotic in the field of medicine it has gained a very vital position in the industrial sector. It is used to treat several bacterial infections due to its innate antibacterial activity. […]
Abstract The adsorption of Congo red (CR) onto carbon prepared from Neem leaf litter (NLLC) and Raw Neem Leaf Litter (RNLL) was investigated. The CR adsorption increased with an increase in pH of the CR solution in high acidic region and then decreased for NLLC, and for RNLL it slightly increased but rapidly decreased in […]
Abstract DNA profiling is a highly conclusive, informative procedure in identification of biological specimens. In the current study, Quantification of DNA was done to detect the concentration of DNA in the samples. Quantity of DNA was calculated by taking the absorbance of samples at 260 nm by Spectrophotometer. In total 100 samples of human scalp […]
