TITLE AND AUTHOR Lab 7 Analysis of purified Concanavalin A via:Hemagglutination INTRODUCTION The purpose of this lab was to test the biological activity of ConA by performing a hemagglutination assay. If ConA is active then agglutination will occur due to ConA’s free receptors being able to bind to the glucose residues on the sheep’s red blood cells. If ConA is not active then no agglutination will occur. To test the hemagglutination reaction‚ two types of ConA solutions

DNA SPOOLING ISOLATION OF DNA FROM ONION INTRODUCTION This project will demonstrate several basic steps required for isolation of chromosomal DNA from cells. To extract the chromosomal DNA‚ both the cell membrane and the nuclear membrane must be broken open. This is accomplished by disrupting the membranes with a solution of detergent and salt‚creating a cell homogenate. Once the DNA is released from the nucleus‚ it must be protected from nucleases‚ enzymes which will degrade the DNA. Keeping

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population‚ and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining
