Candy Electrophoresis Lab

1) We could not analyze the data, for as we went to an assembly, the teacher directed us to keeping the current on, which then resulted in the DNA moving off the gel. By analyzing some other groups gel, which also ran for too long, put some remained, we observed that the red became pink. Because this is not ours, we can not be sure of where the dyes were placed in the gel originally. We could also observe that all the dyes and the standard dyes moved at the same speed, meaning they were at the same place.

2) The Fast Green FCF will go as fast the dye found in Skittles, for the Skittles went the farthest and was green and the name of that dye is Fast Green FCF. We also can think that Citrus Red 2 will go as fast as the Mike n Ike, for those are the same colour.

3) They might put dyes into dog food, so that the dog owner might be more attracted into buying a dog food that is not just brown and might show that it has vegetables or other ingredients.

5) The size of the DNA and the amount of time will affect how far it travels during the experiment. The longer DNA, the less it will go far. Time will let them move the farthest they can.

6) The electrical current helps it move through the gel. They are attracted to the other side so they move.

7) Electricity is the component that causes the DNA to make groups by their size. Because they are repelled the negative charge, the DNA starts its way to the other side. But because the shorter DNA moves quickest, it goes farther, so each length goes a certain distance which can be compared to know DNA.

8) The DNA with the weight of 600 daltons will move faster, for it is smaller meaning it will be able to move the farthest. 5,000 daltons will move the least far, for because of its weight, it will travel very slowly towards the positive charge. From farthest to closest, 600 daltons, 1,000 dlatons, 2,000 daltons, and then 5,000 daltons.

Here is the experiment of the other group that worked.
