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...

Which energy-producing process is thought to have come first during cellular evolution? correct answers Glycolysis The initial importance of a membrane enclosing self-replicating RNA molecules and associated proteins was that it correct answers maintained these molecules as a unit capable of reproduction and evolution. Mitochondria and chloroplasts resemble bacteria in that they correct answers have their own DNA, have their own ribosomes, reproduce by simple division into two. Which of...
