In which type of cell division does spindle formation not occur?

Normally a somatic cell in human beings contains . . . . . . number of chromosomes.

In which phase does $RNA$ and protein synthesis occur?

Select the correct statements.
$A$. Tetrad formation is seen during Leptotene.
$B$. During Anaphase,the centromeres split and chromatids separate.
$C$. Terminalization takes place during Pachytene.
$D$. Nucleolus,Golgi complex and $ER$ are reformed during Telophase.
$E$. Crossing over takes place between sister chromatids of homologous chromosomes.
Choose the correct answer from the options given below:

Identify the correct statements:
$(i)$ Synapsis occurs between homologous chromosomes during Prophase-$I$ of meiosis.
$(ii)$ Centromere division occurs during Anaphase-$II$ of meiosis.
$(iii)$ Spindle fibers completely disappear during Telophase of mitosis.
$(iv)$ The nucleus reappears at the Telophase-$I$ stage of meiosis.
