Polymerase Chain Reaction (PCR)‚ discovered by Kary Mullis‚ has had an extraordinary impact on various aspects of biotechnology. PCR has revolutionized research and diagnostics-based molecular biology. PCR is a simple‚ accurate‚ and highly reproducible procedure. The technology introduced an important advantage to molecular biology. It provides the ability to start with a small amount of DNA and to be able to amplify it so that there will be a sufficient

What are bioengineered foods? Bioengineered foods are plants created for human and animal consumption using the latest molecular biology techniques. Bioengineered foods have been enhanced in a laboratory to desire traits like‚ resistance to herbicides and improved nutrition. By bioengineering foods you can create plants with the desired trait very rapidly. The advantages of bioengineered foods is that they are pest resistances‚ disease resistance‚ able to with stand cold weather‚ drought tolerance

NaCl‚ urea‚ glucose‚ albumin‚ powdered charcoal‚ and KCl. The step by step process was used by the software so that we could see the different kinds of reactions. According to the data found‚ we found that with high molecular weight compounds are too large to penetrate the molecular weight cut off pores and no simple diffusion can occur. So it seemed like the easiest way for a solute to pass through a semipermeable membrane was‚ if it either was small enough to pass or had some sort of carrier protein

Results The objectives of this experiment were to investigate diffusion of molecules across a membrane and the factors that affect the rate of diffusion. The hemolysis time of sheep erythrocytes was measured for each of eight different nonelectrolyte solutions by eleven groups in BI 108 Section D2. These eight nonelectrolytes were urea‚ thiourea‚ methanol‚ ethanol‚ propanol‚ ethylene glycol‚ diethylene glycol‚ and triethylene glycol‚ and the mean hemolysis times can be seen below in Figure 1.

Transformation of E. coli with your unknown plasmid Learning Goals: Insert your uncut unknown plasmid into chemically competent DH-5 E.coli cells and use antibiotic resistance to confirm the success of the transformation. You should familiarize yourself with the various methods of transformation and the advantages/disadvantages of each type. You should also understand how heat shock transformation works and how chemically competent cells make this type of transformation possible. For this transformation

e incorporated a fusion tag prior to our genes of interest and attached the expressed fusion proteins covalently on microarrays. This enhances the specific binding of the proteins compared to nitrocellulose. Thus‚ it helps to reduce the number of false positives significantly. It enables us to screen for immunogenic proteins in a shorter The correct insert size was determined by Colony PCR.

Parés-Matos† *Industrial Biotechnology Program‚ †Department of Chemistry University of Puerto Rico-Mayagüez Campus rachel.hermina@upr.edu December 14‚ 2009 ABSTRACT. Platelet-Derived Growth Factor (PDGF) is one of many proteins that regulate cellular growth and division. The PDGF family consists mainly of five different isoforms called as PDGF-A‚ PDGF-B‚ PDGF-C and PDGF-D. Three
