DNA Applications

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

What applications can gel electrophoresis be used for?

• Parental Testing
• Criminal Investigations
• Sequence Endangered Species DNA
• All of the above
