Gel Electrophoresis Grojean

Shannon does not know who her father is.  There are three possibilities:  Jack, Daniel and Bill.  Who is the father?

• Jack
• Daniel
• Bill

What is the purpose of gel electrophoresis?

• helps cut DNA
• count the genes in DNA
• separates DNA based on size
• allows for an exact replicated organism

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 DNA fragment bands move faster and farther in a gel electrophoresis? 

• there is no way to tell 
• the largest ones
• the smallest ones
• none of these

• Bob
• Sue
• John
• Lisa
