PPT-Assessing the quality and yield of nucleic acids PART 2: gel electrophoresis

1 The spectrophotometer cannot tell you if your DNA or RNA are intact undamaged Vigorous shaking pipetting up and down and vortexing can damage DNA breaking it into smaller pieces To be sure it is not damaged you can run a small amount 100200 ng on a gel .
