Molecular orbital

There are different types of chromatography, and we would be using gel filtration and affinity. Chromatography is defined as the separation of molecules based on properties such as molecular mass, charges or solubility. In Experiment 5.1, gel filtration chromatography was used to separate molecules based on their molecular mass. The stationary phase in the column contains tiny pores, those that are unable to fit into the pores are eluded first; thus, the small molecules are eluded last. We are able

Title: Cloning of Enhancer of Zeste Homolog 2 in forward orientation into Escherichia Coli using histidine-tagged pbluescript II KS+. Abstract Enhancer of Zeste Homolog 2 locus is intensely over expressed in breast and prostate cancer and it’s been established that its promoter inhibition by p53 has led to reduced cell proliferation and invasion (Bracken, 2003; Xiao, 2011). Objective is to clone a forward orientated EZH2 insert into a his-tagged pbluescript. Cloning EZH2 into a histidine-tagged

Exercise 1: Cell Transport Mechanisms and Permeability: Activity 2: Simulated Facilitated Diffusion Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1. Molecules need a carrier protein to help them move across a membrane because You correctly answered: d. they are lipid insoluble or they are too large. 2. Which of the following is true of facilitated diffusion? You correctly answered: c. Movement is passive and down a concentration gradient. 3. Examples

Introduction The movement of water molecules across a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent, each containing different concentration levels, then the water would move along its concentration gradient until each side of the membrane are equal. The water moves because the membrane is impermeable to the solute and the solute concentrations may differ on either side of the membrane. Water molecules may move in and out of the cell, but there is no net diffusion

############################## Part 1 #################################3 Antibody binding of antigens represents a critical part of the adaptive immune system’s ability to identify and eliminate invading pathogens. The antibodies are able to do so due to the binding of their antigen-binding domains to specific epitopes along an antigen’s surface. These epitopes can exist in linear, structural, and

Results and Discussion Effect of mannose on shoot formation of explants As pBCAMBIA-PMI contains the pmi gene which confers mannose resistance, we used the mannose as a selection agent in our transformation experiments. Nine different concentrations and combinations of mannose and sucrose in shoot regeneration medium were used to evaluate the effect of mannose on the organogenesis of non-transformed tobacco leaf explants (Fig. 2). After 3 weeks cultivation, we found that no explants produced shoots

Introduction The central dogma of molecular biology is widely known as the transcription of DNA to RNA, and then the translation of RNA to protein. In these past few experiments, the students looked at mRNA, treated them with PMA and DMSO. The students then performed reverse transcriptase on their mRNAs in order to convert them into cDNA, which is more stable. After that, the students then performed PCR on their cDNA to zero in on the gene of choice. Those genes were then run through gel electrophoresis

The movement of molecules have two forms of transport through the plasma membrane: active transport and passive transport. Active processes require energy, such as ATP, in order for the molecules to be transported. In active transport, the cell administers ATP.i Within passive processes no energy is required and changes n pressure and concentration are the driving forces. Processes such as simple diffusion, facilitated diffusion, osmosis, and filtration are characterized as passive transport, while
