Today in Biology we practiced on loading gel trays with different colored dyes. We used a micro-pipet which held 40 uls to load the trays. Loading the trays in different colors, helped us to see the different types of DNA scientists use.
My group used different colors each time so we didn't have all of the same color for each section. As you can see to the right each color is a solid now.
After we had used the pipet we had to keep changing the plastic that held the coloring so that there wouldn't be any mistake of mixing the colors up.
Each row is a solid and it will remain so until we plug in the electricity. With the electricity the colors will determine which ones are negative and positive energy.
As you can see to the left there is the machine that held the electricity. As i checked back with my group, we noticed that each color was going either the same direction or the opposite. The colors going to the right meant that the DNA was negative. And the DNA going the opposite direction mean that it was positive.
