Question 1.
What is a sticky end?
Show hintHide hint
Think of it as sticky tape that helps DNA bits stick together.
Question 2.
What is a blunt end?
Show hintHide hint
Think of a blunt end like cutting a piece of paper straight across.
3Question 3.
What type of ends do sticky ends have?
- Overhangs
- No overhangs
- None of the above
Show hintHide hint
Think about the stickiness these DNA ends provide.
4Question 4.
Blunt ends are more efficient than sticky ends for ligation.
- True
- False
Show hintHide hint
Recall the comparison made in class regarding binding ability.
Question 5.
You have two DNA fragments: one with sticky ends and one with blunt ends. How would you go about successfully ligating each fragment? Discuss the steps and reasoning behind your choices.
Show hintHide hint
Consider the properties of the DNA ends and how they affect ligation.
Question 6.
Evaluate a scenario in genetic engineering where the choice of blunt ends over sticky ends provides a distinct advantage. Discuss the implications.
Show hintHide hint
Think about cases where sequence-specific integration is essential.
