synaptonemal complex

synaptonemal complex
Structure, identified by electron microscopy, lying between chromosomes during synapsis; consists of two lateral plates closely apposed to the chromosomes and connected to a central plate by filaments. It appears to act as a scaffold, and is essential for crossing-over.
