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 ...
