what is synaptonemal complex
Answers
a ladder-like series of parallel threads visible in electron microscopy adjacent to and coaxial with pairing chromosomes in meiosis.
Answer for Class 11 Biology Students
During Zygotene stage of Prophase 1 Homologous chromosomes come to lie side by side in pairs, the process is called Synapsis. Pairing is so through that all the corresponding points (genes) lie exactly opposite to each other. A pair of homologous chromosomes lying together is known as bivalent or tetrad. A fibrillar organelle called synaptonemal complex develops between the synapsed homologous chromosomes. It is a protein structure that forms between homologous chromosomes during meiosis and facilitates chromosome pairing, synapsis, and recombination.
