Beta-Galactosidase and Western Blot 0 1. EMG 9 and EMG 26 contain strain _lac-_(I- Z+ Y+) and strain _lac -_ (I+ Z- Y-)respectively.Three genes huddled together on the chromosome are required for two strains of _E.coli_ to utilize lactose.Consisting of three genes‚ namely‚ _lacZ_‚ _lacY_ and _lacA_‚ the _lac_ operon orderly handles these genes to code specific enzymes necessary for the metabolism of lactose. The genes _lacZ_‚ _lacY_ and _lacI_ would code for beta-galactosidase‚ galactosidase permease

They study the effects of foods‚ drugs‚ allergens and other substances on living tissues; they research molecular biology‚ the study of life at the molecular level and the study of genes and gene expression; and they study chemical reactions in metabolism‚ growth‚

am considering a major in biology with a concentration in Molecular Biology because of my interest in research. In the past year and a half I have worked continuously at a laboratory‚ first at University of Massachusetts Medical School and then at Cornell. At UMass‚ I became interested in molecular biology because of the work I was doing with the maturation of B-lymphocytes. Because of the educational atmosphere of UMass‚ I became very involved with the graduate students and was on the cutting edge

The Benefits of Nanomedicine Nanotechnology is defined as “the study of manipulating matter on an atomic and molecular scale.” Nanomedicine is the application of nanotechnology within a medical background. Nanomedicine provides us with the technology to quickly and more efficiently diagnose‚ fix‚ and heal the body at an accelerated rate while causing a significantly less amount of harm or stress on the body during the process than current procedures. We are able to achieve this by constructing

biochemical studies that takes advantage of a protein’s amphoteric nature to determine its molecular weight and charge by running the sample through a gel matrix under the influence of an electrically charged field. A popular example of gel electrophoresis is Sodium dodecyl sulfate-polyacrylamide electrophoresis or SDS- PAGE which has been used in this experiment to supposedly determine albumin and casein’s molecular weights respectively. The system used in gel electrophoresis consists of 3 major parts:

GM foods is difficult and the failure rate is high. This is why we (my partner and I) feel GM foods should be banned until scientist’s know ALL the affects Gm foods has on humans and the environment. Genetically modified foods use the latest molecular biology techniques and are commonly used for growing crops for human or animal consumption. GM foods can create specific characteristics of plants or animals‚ such as the ably to withstand weather conditions(temperature)‚ nutrition and they can keep

vertical glass tube over the top of which a stream of vapor-free gas is passed. A water bath is provided for maintaining a steady temperature so that there is no eddy current in the vertical tube and mass transfer takes place from the surface by molecular diffusion alone. The rate of evaporation can be followed by the rate of fall of the liquid surface. A traveling microscope is provided for determining‚ the liquid fall. With the knowledge of the concentration gradient‚ the diffusivity of the vapor

The purpose of this study is to produce recombinant DNA molecules to produce bacteria that would transform into red fluorescent proteins. One plasmid was that allowed to express a red fluorescence was produced by recombining two plasmids by using molecular techniques. Agar plates labeled LB‚ LB/AMP‚ and LB/AMP/ARA containing ampicillin (AMP) and arabinose (ARA) were used to grow of the bacteria of interest and SDS-PAGE gels were utilized in identifying the fluorescent and non-fluorescent proteins
