CHEM 210 Midterm 2 Exam Questions and Answers All Correct Identify the equivalence point on the titration curve. Define the end point of a titration. - Answer-The equivalence point of a titration is reached when the moles of titrant added are stoichiometrically equal to the moles of analyte present in solution. This is observed on the titration curve as the point in the center of the steepest part of the curve, which correlates to the greatest concentration (pH) change per volume of add...

How many base pairs long is a typical gene? - ANS ~10^4bp. What is supercoiling? What is its purpose? - ANS The twisting of a DS DNA helix around itself allowing it to be packaged efficiently into a cell. Why might two sections of DNA which are the same length travel at different rates during gel electrophoresis? - ANS Some of the DNA, but not all, becomes relaxed during laboratory preparation (the state of a circular, non-supercoiled plasmid). Some of the DNA remains supercoiled and so is ...
