Description

Lab #10: GMO Part 2 (Gel Electrophoresis) Pre-Lab 1. (10 points) What is the guiding principle behind gel electrophoresis? a. What does gel electrophoresis say about the DNA samples on it? DNA is more resistant than proteins to processing and can be extracted from highly processed foods. b. Do smaller or larger molecules move further down the gel? Smaller molecules migrate through the gel more quickly and therefore travel further than larger fragments that migrate more slowly and therefore will travel a shorter distance. c. What enables you to visualize the DNA in the gel? electrophoresis d. What is the purpose of the molecular ruler? Molecular rulers are DNA standards with precisely defined size intervals between bands for simplified estimation of the length of nucleic acids separated from the gel e. What enables DNA to move on an agarose gel? Gel electrophoresis of DNA fragments separates them based on size only because all DNA molecules have the same amount of charge per mass....
