I. Objective The first objective of the measurement of thermal conductivity & one-dimensional heat conduction experiment was to identify three different metal specimens by comparing their experimentally determined thermal conductivities to known thermal conductivity values of existing metals. The second objective of the experiment was to establish a connection between the thermal conductivities & temperatures of the metal specimens. Thirdly‚ the contact resistance of the interfaces between

Jamila Bass 814000008 BIOL 1364 Tutorial 1 (Thursday 4:00-5:00 pm) 1. The basic chromosome number (x) refers to the number of chromosomes that are different and separate from all other chromosomes in that organism. The organism may contain one or more sets of this basic chromosome number. The haploid number (n) therefore refers to a single basic chromosome set and are typically found in the gametes of an organism. 2. Mendel’s principles of inheritance suggests that the inheritance of the traits

In this lab we employed various assays utilizing a biuret reagent‚ coomassie brilliant blue reagent‚ and ultraviolet light in order to determine the identity of six unknown solutions and the concentration of a bovine serum albumin sample. We were given three samples that lacked protein‚ and three samples containing proteins‚ and using a spectrophotometer we assessed the amount of light absorbed versus the light transmitted‚ based on the principles of the Beer-Lambert Law. The three proteins used included

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During

To purify the protein in the cell lysate from lab 1 through nickel affinity chromatography. Protein purification should result in only one type of protein ideally‚ which is the protein of interest‚ wt-DHFR and mut-DHFR in this case. A pure protein allows for further analysis on the protein to be conducted‚ such as its concentration (Bradford assay)‚ its molecular weight‚ and its biological activity. 2. Overview of experiments Buffer Preparation Add the liquid sodium phosphate‚ solid sodium chloride

Purification of Green Fluorescent Protein Introduction: Transformation is used to introduce a gene coding for a foreign protein into bacteria. Hydrophobic Interaction Chromatography (HIC) is used to purify the foreign protein. Protein gel electrophoresis is used to check and analyze the pure protein. Research scientists use Green Fluorescent Protein (GFP) as a master or tag to learn about the biology of individual cells and multicultural organisms. This lab introduces a rapid method to purify

Lab2: Testing for Proteins and Starches In this lab 8 total substances were tested to find out whether they are a Protein or a Starch. It is my belief that only 1 or two of each of the substances in test 1( proteins) and test 2 (starch) will test positive for either protein or starch. For this lab the following materials were needed to complete the experiments in test 1 for proteins: Di water‚ ev milk‚ 50% egg solution‚ 1% sucrose‚ 4 test tubes‚ 1 test tube rate‚ safety glasses‚ pipets and
