Write brief note on the following:
Synaptonemal complex
उत्तर
Protein makes up the synaptonemal complex. During meiosis, it is formed between two homologous chromosomes. Pairing, synapsis, and recombination all take place here. The homologous chromosomes are paired through the synaptonemal complex during prophase – I of meiosis. This complex facilitates the exchange of genes. Synaptonemal complexes play a role in the recombination of genetic characters.
