Focus Questions

1.) No, all the dies matched another base dye that we knew.

2.) All these molecules look similar to the dyes and these molecules look like they produce the same dies.

3.) Don't dogs see in different shades of gray? But maybe these different shades of gray appeal to the Dog or Cat.

4.) surprisingly, I do not consume any dyes at all. }I looked at all the food I usually eat and they all said no artificial dyes. Artificial dyes are added to appeal to people and make food look good.

5.) The two factors that control the distance of the colored dyes is the size of the molecules and strength of the electricity.

6.) Electricity moves the dyes through the gel.

7.) The heavy molecules get left behind due to size and weight, and the small dyes move ahead.

8.) The weight of the DNA heavily affects of the distance traveled.
