Answer: 4. Sites at which crossing over occurs

Recombination nodules are protein-rich structures seen in the pachytene stage on the synaptonemal complex, and they mark the sites where crossing over takes place.

The synaptonemal complex is the zipper-like structure itself, a bivalent is the paired homologues, and terminalisation is the movement of chiasmata to the ends in diplotene.
