1. What’s the diameter of the ball? Need hundreds' digit in cm like x.xx cm (4 points)
2. Suppose your group have run an agarose gel containing control DNA +/+, +/- and -/-. Besides,
they run their own DNA as well. It is known that Ming’s genotype is +/+ while Andrew’s genotype
is +/-. After half hour, what should you see on the gel? Draw a graph of these 5 bands on the gel
( DNA runs from black lead to red lead ). You need to note both black side and red side. (6 points)
