Copy, Cut, Edit, Sort

You'll learnwhich biotech tool copies, cuts, edits, or sorts DNA, and why each is distinct.

Unit 6 spent seven topics watching the cell handle its own genome. This is the one where you pick up the pipette. Watch a restriction enzyme cut at its own fixed address, ligase seal the join, PCR double a target until one molecule becomes a billion, and CRISPR send the same scissors somewhere new — then watch the mistake this topic exists to kill, which is reading a gel backwards. Eleven short steps; press Next for each one.

Before you start

What you're looking at

A piece of DNA and the four things a bench lets you do to it: copy, cut, edit, and sort the pieces by size.

The question

Which tool owns which verb, and why does a gel put the small fragments farthest?
