    1. Why is the separation of the lower bands incomplete?
    2. What are the overhangs on the DNA ladder fragments? Can I end-label them using the T4 polynucleotide kinase (PNK)? What about the Klenow fragment?
    3. How can I quantify the amount of DNA in each band of a marker?
    4. Can I use GelRed with the DNA Ladders from NEB?
