Solution
Answer: Option D
Solution:
Synaptonemal complex is composed of a dense central element, two relatively dense lateral elements and two relatively less dense transverse elements.The synaptonemal complex (SC) is a protein structure that forms between homologous chromosomes (two pairs of sister chromatids) during meiosis and is thought to mediate synapsis and recombination during meiosis I in eukaryotes.
The synaptonemal complex is a tripartite structure consisting of two parallel lateral regions and a central element.
