Candy Electrophoresis Lab Questions

When we did the green dye, there was an interesting discovery that we found. We discovered that when the green dye migrated, it separated into a blue and yellowish dye, in the same band.

The citrus red 2 dye is similar to the dyes in the lab because the structure of the citrus red 2 dye is similar to the structure of the red 40 dye that we used in the lab. Since the structure and the size of the two dyes are similar, then that means that the distance that it moves would be about the same.

The reason that some dog food manufacturers is because that the different colors could attract the dogs to eat the food. Another reason for this is that the food coloring in the dog food could make the food look more appetizing for the dog.

The reason that the people might use artificial colors over food colors because they can become brighter or more colorful without the use of a lot of the dye. The artificial color is cost effective and that is why manufacturers use artificial.

The two things that control the distance that the dye travels is size of the pieces along with the structure of the dye. These two control the distance because if the piece is smaller, then it travels farther.

The force that helps the dye move through the gel is the electricity that is running through the gel. (Negative and Positive charges)

The holes in the gel allow the molecules to separated by size. The way that this works is the smaller the molecule, the faster it can navigate through the dye and the farther they go.

The DNA molecules with those weights will separate through the holes, but some will just take longer to migrate.
