The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation‚ the process in which a cell takes up and expresses a new piece of genetic information‚ the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their

Clement Organic Chemistry 2423‚ Section 304 25 October 2017 Lab 6: Natural Products I The main goal of this experiment was to employ isolation techniques to derive chemicals from two different natural sources and study their properties (Clement 91). The two natural sources used in this experiment were an orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol

Interphase: DNA has formed already‚ but it remains in the simple form of chromatin. Chromatins are structures that are loosely coiled in the cell.3 I also observed during my lab that this was the only stage where I could still see a nucleus and nucleolus intact within the cell; this is because it’s the only stage where the nuclear membrane has

Introduction In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role‚ if any‚ that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and

EXPERIMENT I Photoreduction of Benzophenone Introduction The study of chemical reactions‚ isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for

Chemotherapeutic Agents of Control: Introduction: Chemotherapeutic agents are chemical substances used to treat various forms of infectious diseases. The chemotherapeutic agent works by stopping the bacteria from reproducing. There are two different kinds of chemotherapeutic agents. The first kind is an antibiotic‚ which slow down the growth of microorganisms. The second kind of chemotherapeutic agent is synthetic drugs. Synthetic drugs are artificially made in a laboratory.
