Question

Synaptonemal complex. Select all that apply. Select all that apply. It is a layered structure located between paired homologs in prophase I of meiosis in many organisms. It catalyzes the phosphorylation of specific proteins. It is complex structures attached to the centromeres of chromosomes that bind to spindle microtubules It is required for moving sister chromatids to opposite sides of the poles during anaphase II of meiosis and anaphase of mitosis. It is important for maintaining homologous chromosome pairing and plays a role in recombination.

Answer 1

Answer:

The correct answer will be options-

1. It is a layered structure located between paired homologs in prophase I of meiosis in many organisms.

2. It is important for maintaining homologous chromosome pairing and plays a role in recombination.

Explanation:

A synaptonemal complex is a complex protein structure formed between the pair of sister chromatin.

The complex is composed of synaptonemal complex proteins 1, 2 and 3 where formation begins in the zygotene and completes in pachytene stage of prophase I of meiosis I during which the complex along with chromatin forms a zipper structure.

Formation of synapsis allows the pairing of chromosome between two sister chromatids and mediate the process of recombination.

Thus, the selected options are the correct answer.
