We are used to using a 1.5% agarose solution, so if the solution is 1%, would a longer band or shorter band move faster in gel electrophoresis?
Homework Answers
Agarose concentration affects the separation of molecules in gel electrophoresis. Increasing the agarose concentration decreases the speed of longer bands while decreasing the agarose concentration facilitates faster movement of shorter bands. It enables separation of larger molecules

Agarose gels are created by dissolving powdered agarose into liquid buffer. We will be using a 0.8% agarose gel (weight in grams/volume in mL). If each gel is made using 100ml of buffer, how many grams of agarose are used? Show your work!

This week we will run the PCR reactions on an agarose gel and analyze the results. Safety notes: Ethidium bromide is a potent mutagen. Wear gloves when handling containers containing ethidium bromide, when handling gels that have been stained in ethidium bromide, and when working with the computer attached to the gel-doc system.

3. The given figure represents the agarose gel electrophoresis results from a restriction digest experiment. Lane 1 is a DNA ladder (values are in kb) and Lane 2 is the DNA sample cut by a restriction enzyme.

Human genomic DNA is around 3 billion bps. Why do we see a band around 10kb in 1% agarose gel electrophoresis? Did we do something wrong, damage the DNA and shorten it or something, what kb shall we expect to see it?

Why do restriction enzymes need to be kept on ice? What order should the DNA, enzyme, water and buffer be added to the microcentrifuge tube for a restriction digest? If lambda DNA is linear, how many times would the enzyme have to cut the DNA to generate five DNA fragments? Would a shorter DNA fragment move faster or slower through the agarose gel than a longer fragment? Why?

Do not calculate the solution to this problem but show how it would be set up. Assume you are trying to create a gel for gel electrophoresis that had a 1.2% concentration of agarose. If you had 50X TBE as the liquid buffer and the gel size was 20mL, how much 50X TBE would you need? How much water? Receptors in the medulla of the brain will stimulate respiration when hydrogen ion concentration increases. Normal blood pH is 7.4. If...
