Bacterial Transformation Lab Report Title: Bacterial transformation lab Objective(s): The length of the time for which the heat shock is given greatly affects the process of transformation or the uptake of the plasmid by the bacterial cell. Hypothesis: As the length of the time of the heat shock increases there are greater chances of the process of transformation or the uptake of the plasmid by the bacterial cell. As the time period of heat shock increases, the bacterial cell membrane deve...

You want to clone a DNA fragment that has been digested with BamHI into a plasmid vector. What should you do to prevent religation of the vector? If you don't do this what other problems will occur? Correct Answer-To prevent religation you should treat it with alkaline phosphatase which will knock off the 5' phosphate. As a result you will have 5' and 3' OH which means ligase can't act on it. If you don't, you could get a concatemer or the insert could go in upside down or backwards. ...
