I keep getting “Restriction enzymes” questions wrong in Biotechnology - Principles and Processes. What's the trap?
thinking they cut DNA at random positions.
The usual trap: thinking they cut DNA at random positions. How to avoid it: a restriction enzyme cuts at its own specific palindrome -> matching sticky ends. Go back to the definition — molecular scissors that cut DNA at a specific palindromic sequence, often leaving single-stranded sticky ends.
