i) What is synaptonemal complex?
ii) Explain the significance of crossing over with diagram In
which phase of cell division this process takes place?

C. Muthu Kumari · Accepted Answer

Dear Student,
(i) The synaptonemal complex is a protein structure formed
between two homologous chromosomes during meiosis The synaptonemal
complex mediates chromosome pairing or synapsis
(ii) Crossing over occurs during Prophase I of meiosis Crossing
is mainly responsible for the genetic difference Crossing over is
the exchange of genetic material between two homologous chromosomes
with the help of enzyme recombinase It results in
recombinant homologous chromosomes
