Chapter 1 DNA‚ RNA‚ Historical Experiments & Structures Frederick Griffith Experiments with Streptococcus pneumoniae S. pneumoniae comes in two strains‚ smooth and rough strains S Smooth : Secrete a polysaccharide capsule; Protects bacterium from immune system of hosts; Produce smooth colonies on solid media. R Rough : Unable to form capsule; Produce colonies with a rough appearance. Griffith conducted experiments in 1928 using two strains of S. pneumoniae: type IIIS and type IIR : 1. Inject

most any material. GOOD LUCK! Abstract: In this lab we determined the freezing point‚ and Kf‚ of pure 2‚4‚dichloralbenzne as well as a 2‚4‚dichloralbenzne/biphenyl solution. We used this information to determine the molar mass of an unknown (#24) by the 3rd step in the experiment which was a 2‚4‚dichloralbenzne/unknown solution. All of the above we charted the time temperature for the later calculations. I. Introduction A. Background This experiment shows how one determines the temperature-composition

performed using students in a BIOL 3600 laboratory. Buccal cells were extracted from the BIOL 3600 students‚ later purified‚ and then cut with two restriction endonucleases‚ MseI and RsaI. The now cut DNA was mixed with a blue loading dye and run on a 1.0% agarose gel (with added TAE buffer and Sybr Safe) at 110 volts. The finished product had bands of diverse base pair lengths‚ differing from student to student. During the RFLP analysis

Heat & Mass Lab 1: | | | 2/10/2011 2/10/2011 Executive Summary This experiment was conducted using a heat transfer unit. Many relationships were obtained and calculated from the observed results. To name a few; the log mean temperature difference‚ heat transfer coefficient‚ Reynolds‚ Nusselt and Graetz numbers. The main focus of this experiment is the heating and cooling of the oil fluid. This was achieved using the heating component in the heat exchanger and water flowing

17 May 2013 Are Protein Shakes Good For You? According to Flex bodybuilding magazine‚ protein shake is the number one selling bodybuilding supplement. Protein powders have been around for years‚ but they are currently gaining popularity and becoming more widely used for their health benefits. In fact protein is one of three food components we require in large quantities. Others are carbohydrates and fats. Your body uses proteins in your diet to build new cells‚ maintain tissues‚ and synthesize

Objective: To investigate how pH affects the rate of protein digestion Hypothesis: I predict that since pepsin breaks down the material the quickest at a pH of 2 in the stomach‚ test tubes #3 will reduce the greatest because it has pepsin to further break down the egg. Whereas the other test tubes will have a smaller reduction. I think test tube #2 will have the second largest reduction rate and then #6 because they all will have a greater rate at breaking down the material‚ Then‚ I predict the
