Introduction The purpose of this lab was to demonstrate the use of gene therapy on diseases that are caused by a single gene defect. This procedure was demonstrated on two different strains of baker’s yeast‚ EAY 235 and EAY 431‚ which both contained mutations in the LEU2 and TRP1 genes. Neither of these strains will grow without a proper medium that would supply both of these essential amino acids. The EAY 431 strain of yeast also contained a Rad 52 deletion‚ which caused EAY 431 to be a deficient

Evolution Lab Report Marcos Chapa July 3‚ 2013 BIO 101 Rebecca Avants The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other‚ placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island‚ which is 1 km‚ and the other population of finches

If pH > pI‚ then the protein will have a negative charge and if pH < pI‚ the protein will have a positive charge. Buffer I has a pH >5‚ meaning both proteins carry a negative charge and bind to the DEAE (a positively charged resin). (b) pH = pKa + log10(Base/Acid) [Base = mM of sodium acetate; Acid = mM of acetic acid] = 4.7 + log10 (40/40) = 4.7 In order for the catalase to elute from the column‚ it must have lost its negative charge and stopped binding to the DEAE. Lowering the pH nullifies

acid) has been added to the acid (or the base). The end point is frequently detected using a visual indicator. An acid-base indicator is a substance‚ which changes colour with pH. For each type of acid-base titration‚ an appropriate indicator must be chosen. However‚ the end point can also be determined potentiometrically using a pH meter or by a conductometric method. At this point‚ all the acid has been neutralized and neither excess base nor excess acid is present in the solution. The solution consists

Physics Lab report Aammar Paracha Section MX Feb 6th 2015 OPTICS Abstract: This experiment revolves around using light rays and lenses. The experiment also discusses different properties of light rays. This experiment uses different lenses and measurements to produce images and observes different techniques to obtain the image position. Question and Answers: 1. Use your data to verify the Law of Reflection and then use Snell’s Law to calculate

The results above show group wajaisha from class 1a obtained different results compared to my group. Wajaisha’s group used pH 4 and my group also used pH 4. The results that we obtained were after five days we had 35 cells present however wajaisha’s group obtained 42 cells after five days. My group obtained a value of 28000000 per litre and wajaisha’s group obtained 33600000 per litre. Our results may have been slightly different due to us not being able to record the number of cells present on the

Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order of weak acids and

Enzymes Ashley Njeru Mrs. Booth Tuesday‚ March 19th 2013 SBI 4U INTRODUCTION: The cellular activity of all organisms is controlled through the use of enzymes. An enzyme is a special type of biological molecule‚ usually a protein‚ which speeds up a chemical reaction; most are soluble in water or a dilute salt solution. There are about 4000 different enzymes in a typical living cell. If even one of these enzymes is missing or
