Question

The synaptonemal complex is completely formed during which phase of cell division?

• A. Leptotene of Prophase I
• B. Zygotene of Prophase I
• C. Pachytene of Prophase I
• D. Diplotene of Prophase I

Answer 1

The correct option is C Pachytene of Prophase I

Synaptonemal complex is a protein complex that holds together the homologous chromosomes together to facilitate crossing over or genetic exchange between their non-sister chromatids.

Its formation begins during the zygotene stage of Prophase I of Meiosis I and is completed during the Pachytene stage.

So, the correct answer is 'Pachytene of Prophase I'.
