DNA Isolation from Onion! Today‚ the students are going to isolate DNA from onions. You will need a blender or a food processor for this experiment. If you do not have one‚ check to see if your teacher does. If neither of you have one‚ then let me know ahead of time‚ and I can provide one from my home. You will also need to bring a knife and cutting board to cut the onions as well as a measuring cup. All other materials will be provided. The first part of the DNA experiment is to grind

Absorption Spectroscopy Author: Lab Partners: Instructor: Chem 152 Date Work Performed: Date Work Submitted: Abstract A Beer’s Law analysis was used to determine the molar absorptivity of a Red-40 food dye. Using a spectrometer‚ the best wavelength to use for the analysis of this dye was determined to be 501nm. A series of dilutions were performed and the concentrations were calculated to find ‘E‚’ the molar absorptivity‚ which was determined to be 18035 M-1 cm-1. Introduction

Steven‚ I think firearms identification is quite fascinating and intriguing as well. I too‚ own several firearms and find them to be empowering to say the least. What is more amazing to me is how the markings on a bullet are as specific to a weapon as fingerprints are to a person. Just like fingerprints of an individual each bullets marking are as unique and identifiable as the gun it was projected from. Yet‚ alterations can be made to such markings as a result of the things a bullet may pass through

Practical guide to detection and identification of Phytophthora Leaf blight A number of Phytophthora species cause leaf blight. These include: P. infestans on potato and tomato; P. palmivora on a large number of tropical fruit species including rubber‚ durian and macadamia; and P. colocasiae on taro. These blights on leaves are first seen as small flecks but within 3-5 days they expand to produce large lesions. Initially‚ infected tissue is water soaked but becomes necrotic (brown or black) in
