Homework Answers
DNA is negatively charged. If you run DNA sample in a gel under constant voltage, the smaller fragments will migrate faster whereas larger fragments migrate slowly.
Note: The electrophoretic migration velocity (
up=μpE. E is constant

-Understand the concept of (restriction enzyme produced) DNA fragment separation by gel electrophoresis. -In gel electrophoresis, which DNA fragment (in terms of size) would migrate further from the sample well? -Understand restriction enzyme(s) and recognize they leave blunt or sticky ends (ie. XbaI, SmaI, EcoRI, BamHI)? -Understand the steps (process) of the Polymerase Chain Reaction and Thermal Cycling. Please answer as much as you can and I will give a high rate

Topic II. Separations methods in the CH455 lab. Describe how the capillary electrophoresis experiment is able to separate both charged and neutral species using electrophoretic and electroosmotic modes of separation. Use diagrams to assist in both the description of the phenomena and provide representative examples of separations achieved with CE.

Biologists use gel electrophoresis to sort DNA segments by size. DNA segments are placed at one end of a gel. DNA is negatively charged (with a charge of two electrons per base pair). When you “run the gel” you are generating an electric field by connecting anodes and cathodes at the ends of the gel. This causes the negatively charged DNA segments to move towards the positive electrode. After running the gel, smaller DNA segments have moved farther from the...

Question 4-12 points Biologists use gel electrophoresis to sont DNA segments by size. DNA segments are placed at one end of a gel. DNA is negatively chargod (with a charge of two electrons per base pair). When you "run the gel" you are generating an electric field by connecting anodes and cathodes at the ends of the gel This causes the negatively charged DNA segments to move towards the positive electrode. After nunning the gel, smaller DNA segments have moved...

Describe what DNA pattern is expected to be seen on the gel electrophoresis after MNase digestion and explain why and How do you expect the DNA pattern observed on the gel electrophoresis to change if you increase the amount of MNase added during the MNase digestion step?
What is the purpose of gel electrophoresis? How is size related to movement through a gel?...
What is the purpose of gel electrophoresis? How is size related to movement through a gel? What is a DNA ladder? Why is it important in gel electrophoresis and how is it used? (note: a ladder is also called a “standard”) What are two indications one can look for to be certain the gel electrophoresis is occurring? What are two strategies to improve the resolution of DNA bands?
