Separation of Proteins and Mass Analysis Using SDS PAGE Biology 00-01L Abstract This experiment consisted of separating proteins into polypeptides using a method called SDS PAGE which is a type of electrophoresis. The polypeptides had different masses‚ so each polypeptide traveled a different distance and this was an essential part of the lab which demonstrated that there exists a relationship between the distance traveled by the protein and the mass of the protein. This relationship was graphed

Introduction: Water’s ability to stick to itself is surface tension. In this lab we were able to measure and detect surface tension by dropping water‚ drop by drop‚ onto a penny. The quantity of droplets that fit on the penny was impressive. Hypothesis: The detergent will thicken the water making a tighter surface tension. Prediction: If soap increased the surface tension‚ then expansion will happen. Materials: (1) Pipette (2) Water (3) Penny (4) Liquid Soap Method: Retrieve materials‚

PROTEIN TRANSLATION 1. Initiation Translation To begin translation: large and small ribosomal subunit‚ along with the initiating tRNA‚ assembles onto the mRNA 2. Translation Elongation The next amino acyl-tRNA enters the ribosome at the A site The amino acid at the P site is transferred to the tRNA at the A site. The ribosome moves one codon farther along the mRNA‚ releasing the empty tRNA through the E (exit) site. The A site is free for the next incoming RNA. The cycle is repeated as the

Derricka Joe Period 5 1 Oct.‚ 2014 Lab Experiment One: Physical Properties Lab Analysis: For our first unknown‚ we observed the color and odor of the substance. The substance was a clumpy‚ white‚ crystal-like substance and it smells like new plastic. When we tested the solubility in water it resulted insoluble and in ethanol it resulted soluble. This substance could not be tested for electrical conductivity because the water was insoluble. We then tested for the PH value and it was neutral. The

You have to know what the products and reactants are. 2. What observations might you make that suggest that a chemical reaction has occurred? If a gas is produced or precipitates are formed that indicates chemical reaction. Also‚ if color changes occur or

the electrons as a back donation to the pi orbital in DMSO. In the first experiment‚ I had to synthesized CuCl2~2DMSO to determine which DMSO atom; Sulfur or Oxygen‚ combined to Copper (II) Chloride. I was able to determine it base on finding the melting point and observing the Infrared Spectroscopy. Since copper is a hard metal‚ it will most likely bond to an oxygen atom because they are both hard. In the second experiment‚ I also synthesized RuCl2~4DMSO to determine which DMSO atom; Sulfur or Oxygen
