Question

During zygotene stage of meiosis in a spore mother cell, a proteinceous structure which appears between homologous chromosomes is known as.

• A. Histone complex
• B. Lysosomal complex
• C. Liposomal complex
• D. Synaptonemal complex

Answer 1

The correct option is D Synaptonemal complex

• The synaptonemal complex forms during the early stages of meiotic prophase I zygotene, when it mediates the pairing of homologous chromosomes.
• Synaptonemal complex in chromosome synapsis and genetic recombination plan an important role. The synaptonemal complex is a proteinaceous structure and is thought to mediate synapsis and recombination during meiosis I of eukaryotic cell division.

So, the correct option is 'D'.
