Specificity of Albumin Binding

In this experiment we used electrophoresis to study the binding interactions that occure between serum albumin and two synthetic dyes. The dyes were Bromophenol Blue and Ponceau S. The basis for this procedure was the observation that the free dyes not bound to albumin migrate faster than albumin or dyes bound to albumin. Important: In the electrophoresis gel there are two wells that have the number 4 tube because someone in our group accidentally filled up two of the wells with tube #4 mixture. If you have any questions please contact me. See attached file for full problem description.

Cell Biology

1. While using a compound microscope, you observe a cell that is undergoing mitosis. You see double stranded chromosomes and a partial nuclear membrane. What phase is this cell in? 2. You are examining a slide showing cells undergoing mitosis. You see a cell in which a centriole is at each end of the cell and single stranded chromosomes are about halfway between the midregion of the cell and each centriole. What stage is this cell in? 3. Why would it be important for daughter cells to receive a portion of the cytoplasm during cells reproduction?

Cell Biology

1. How do evolutionary biologist explain why there are two different ways of handling the pyruvate produced from glycolysis? Be sure to relate your answer to the nature of the Earth 3.5 billion years ago. 2. Explain at a biochemical level how wine is made and compare it to your activity of rapidly opening and closing your hand.

Cholera

Why does a solution of sugar and salt needed to be administered for a person that has cholera? Why can't a person just drink a solution of just salt or just sugar?
