Why does DNA move through the gel matrix when electrical current is applied to the gel?
Because the DNA is attracted to electrical current.
What factors affect the rate at which DNA fragments move through the gel?
Would you expect DNA pieces of a particular size to move faster or slower in a gel with a higher percent of agarose? Explain why.
Would you expect DNA pieces of a particular size to move faster or slower in a gel with a higher percent of agarose? Explain why.
The DNA ladder provides a reference for the size of the DNA. Why do you think control samples are also usually run?
