Which of the following is a false statement regarding the separation of DNA fragments using gel electrophoresis? A dye is added to the DNA sample, gel and buffer and can fluoresce when exposed to UV light, thus allowing the DNA fragments to be visualized. A pH gradient is created within the agarose gel allowing for the separation of DNA fragments based on their isoelectric point. Since nucleic acids are negatively charged, DNA fragments will migrate towards the positively charged electrode DNA fragments are separated from each other according to relative size with smaller DNA fragments migrating faster through the agarose gel than larger fragments.

Which of the following statements about gel electrophoresis is false? Choose all that apply. Smaller DNA fragments travel faster and further during gel electrophoresis. DNA fragments can be separated based on fragment length. DNA fragments can be separated based on DNA sequence. Larger DNA fragments travel faster and further during gel electrophoresis.

Which of the following is an incorrect statement concerning gel electrophoresis? The smallest pieces of DNA will travel further and faster. Gel electrophoresis relies on the fact that DNA is positively charged. When running a gel, there are opposite charges on each end of the plate. Gel electrophoresis separates DNA based on size.
