Problem:
Question: How does high pH affect human DNA? and what will happen if the pH is lowered back to neutral? Explain thoroughly.
Question: Within monolayer, lipid molecules exchange places with neighbors every 10^-7 seconds. If we assume that the diameter of a lipid head goup is 0.8nm, what is the shortest time, theoretically, that it would take a lipid molecule to move from one end of a bacterium to the other end of the bacterium, a distance of 2um? Show the pedigree and your calculation.
