Natalia Rey 080927440 BI338 Lab 1 Measuring the Success of Pisum sativum leaf cell fractionation: SDS-Polyacrylamide Gel Electrophoresis and Western Blot Analysis Introduction In order to evaluate the success of cellular fractionation‚ there are various methods that can be implemented that target specific proteins and/or receptors specific to particular organelles. SDS-PAGE (sodium dedocyl sulfate- polyachrylamide gel electrophoresis) is a technique used to separate proteins based on

Testing Cell Transportation Across a Membrane Introduction Cells have the amazing ability to transport certain molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live

The purpose of this lab was to hypothesize about membrane traffic in lab‚ explain the differences between the solutions hypertonic‚ hypotonic‚ and isotonic and how they respond using the understanding of the cell membrane structure‚ types of transport mechanisms such as active‚ passive‚ diffusion‚ osmosis‚ and explain the movement of particles moving across the cell membrane. In this lab was divided into two parts. The first part was varying the concentration and the second part was varying the temperature

Biochemistry Introduction DNA is a double-stranded molecule of polynucleotide chains twined/twisted together into a double helix structure. This molecule is the one that forms the genetic material responsible for transfer hereditary genetic information from one cell to another during cell division. RNA is a single-stranded molecule that contains polynucleotide chain used for the transfer of genetic information especially in bacteria cells (Freifelder‚ 2002).

During my research‚ I focused my efforts on the size and location‚ research opportunities‚ and values of my prospective college and New York University appealed to all three categorizes and more. I want to major in biochemistry at the Biochemistry and Molecular Pharmacology. Specifically‚ I am interested in studying neuroscience. I was born with Erb’s Palsy‚ an injury that damaged a portion of the nerves of my brachial plexus and left my right arm paralyzed. It took years of therapy
