Question

What is the main structural component of the synaptonemal complex?

Answer 1

Synaptonemal complex:

1. A complex structure formed in the zygotene stage of the prophase of meiosis I .
2. The complex is formed between non-two sister chromatids of two homologous chromosomes.
3. The complex shows synapsis or pairing between homologous chromosomes.

The main structural component of the synaptonemal complex:

1. The transverse filaments are the main structural component of the synaptonemal complex.
2. The transverse protein of the synaptonemal complex is composed of Zip 1 protein in yeast and SYCP1 protein in mammals .
3. Both Zip and SYCP1 in the mature synaptonemal complex are composed of transverse filaments that are oriented perpendicular to chromosome axes.
