In AP Biology we will doing one of our required labs. This lab is the restriction enzyme and gel electrophoresis lab in which student will prepare an agarose gel to separate DNA fragments from lambda cut with restriction enzymes (EcoRI and HindIII). Given the size of the standard they will use log paper to calculate the size of unknown fragments ... In this lab students learn about the science of separation by using electrophoresis.
We did some background work today about restriction enzymes ... where they come from and how they work. This lab links to our other biotech lab next week ... bacterial transformation lab.
In selected topics today we worked on ACT science questions and started our catapult lab ... we will building catapults on Monday and having our competition on Wednesday of next week. We have moved from astronomy into our physics unit.
Practice today for the most part was at BSA ... live hitting, tees and cage work. We had to move to the gym at 4:30 to finish practice.
We will have to go to Plan B tomorrow in practice ... I will send something out by noon.
