Challenge Problems
Push your limits with challenges.
Question 1
If you have a DNA sequence cut by a restriction enzyme resulting in fragments 500bp, 200bp, and 300bp, how would gel electrophoresis visualize these fragments? Predict the order based on size.
💡 Hint: Remember, smaller pieces move faster in the gel!
Question 2
Given that restriction enzymes can create sticky ends or blunt ends, discuss the advantages of using sticky ends in DNA ligation. Why are they often preferred?
💡 Hint: Think about how puzzle pieces fit together—sticky ends are like pieces that have edges fitting into each other.
