Understanding Gel Electrophoresis

This laboratory procedure is known as

• CLONING

• gel electrophoresis

• chromatography

• use of a dichotomous key

In gel electrophoresis, the largest DNA fragment will appear

• closest to the starting wells
• farthest from the starting wells
• three quarters away from the starting wells
• it depends on how many fragments there are

Why do the fragments of DNA in gel electrophoresis travel away from the negative electrode?

• DNA is negatively charged so attracted to the positive end of the unit
• DNA is positively charged to attracted to the negative end of the unit
• the agarose gel in negatively charged
• the agarose gel is positively charged

Which two bat species are most closely related?

•  Bat 1 and Bat 2
• Bat 1 and Bat 3
• Bat 2 and Bat 3
• There’s no way to tell
