Vedclass · Answer

(C) The synaptonemal complex is a protein structure that forms between homologous chromosomes during the pachytene stage of prophase-$I$ of meiosis.It facilitates the pairing (synapsis) of homologous chromosomes and is essential for crossing over.Therefore,the Assertion is correct.However,the synaptonemal complex is specific to meiosis,not mitosis.Mitosis involves the division of somatic cells where homologous chromosomes do not pair up or form a synaptonemal complex.Thus,the Reason is incorrect.

$A$: Synaptonemal complex develops between two synapsed homologous chromosomes.
$R$: Mitosis cannot be completed without the synaptonemal complex.
