Abstract: Oceanitis G.W’s main goal through this project is to open the eyes of our school, California, the United States, and the world, to the adverse effects of oil spills and a revolutionary way of cleaning them up. We plan on demonstrating the usefulness of hair and how it absorbs crude oil when haphazardly spilled. Also, we plan to demonstrate how hair can be used as a type of fertilizer before and after it has soaked up oil. This activity is meant to show that the current methods of cleaning

Cell Membranes and Transport Hands-On Labs, Inc. Version 42-0033-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing

IB SL Biology Lab Molecular Biology: Transformation and Electrophoresis Christina Qi 2/16/07 Aim: How can a plasmid be engineered to include a foreign piece of DNA and how does gel electrophoresis separate DNA molecules present in a mixture? Hypothesis: If the pGLO plasmid is inserted into competent Escherichia coli cells, then the transformed bacteria will be resistant to ampicillin and will glow green under UV light. If samples of DNA are cut using certain restriction

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane, in a phospholipid bilayer. Phospholipid molecules form two layers, with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid, and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable, and allows oxygen

practical exercise you will be using biuret reagent.  Why is biuret reagent used in this practical? The biuret reagent is used to assess the concentration of the protein because peptide bonds occur with the same frequency per amino acid in the peptide. The intensity of the colour, and therefore the absorption, is directly proportional to the protein concentration. Q 2.     What is the experimental reason for constructing a standard curve? Multiple samples with known properties can be measured and

Biology II Step 1: How will you identify the “vital” cellular protein that the virus targets for degradation? (Hint: think proteomics). (3 pts.) First, since we know the viral RNA sequence and its targeting protein, we can investigate it in bioinformatics database, and can acquire some clues or hints about the target proteins. From the bioinformatics database, we might be able to find its structure, similarity with other proteins, functions, and binding domains. In other words, we can get some

of hydrolysis in action within our bodies is how our body breaks down protein into amino acids. Water is used to break protein down in to its amino acids. Condensation- Condensation is when two molecules combine and form one bigger molecule. It is exact opposite process of hydrolysis. It is also

fuse with the plasma membrane in a process called exocytosis. James Rothman discovered that “this process is done very precisely as specific protein complexes on the transport vesicles and specific proteins on the plasma membrane bind together to cause this fusion” (1). When the cell takes in particles from the outside, the cell sinks inward

of phospholipids, each comprising a hydrophilic head and a hydrophobic tail, gather, they rearrange into what is known as a Fluid Mosaic plasma membrane (Reece et al., 2011). This membrane is always in motion and the mosaic created is due to the proteins within the membrane (Reece et al., 2011). Additionally, the membrane is also selectively permeable which means that not every substance moves across the membrane (Reece et al., 2011). Factors such as the polarity of a molecule and the relative size

Eukaryotic cells rely on the ubiquitination of proteins for the proper control of their internal processes. Adding multiple ubiquitin groups aids in the breakdown of proteins, whereas adding only one ubiquitin serves regulatory roles other than degradation. The enzymatic activity of two protease classes frees ubiquitin groups from associated proteins: Ubiquitin specific proteases (USP) and Ubiquitin C-terminal hydrolases (UCH). USPs are strongly involved in eukaryotic cellular functions and are
