Fill in the blanks
During metaphase, spindle fibres attach to ________.
Centromeres split and chromatids __________ during __________.

Arrange the following statements on meiosis in a correct sequence.
A) Terminalisation of chiasmata.
B) Dissolution of synaptonemal complex.
C) Homologous chromosome separation.
D) Appearance of recombination nodules.
E) Pairing of homologous chromosomes.
F) Disappearance of nuclear envelope.

Assertion $\left(\mathrm{A}\right):$ In crossing over, the exchange of genetic material between two homologous chromosomes occur during both mitotic and meiotic cell divisions.

Reason $\left(\mathrm{R}\right):$ The process of crossing over is only possible and is mediated by recombinase.

The correct answer is:

Match the changes which occur in the chromosomes during meiosis, with the different phases of prophase-I.

The correct answer is
