Which chromosome may be lost during cell division?

Statement $P$: The $G_1$ phase is the final phase of interphase.
Statement $Q$: $DNA$ synthesis occurs in the $G_2$ phase.

Identify the correct statements: $(1)$ Synapsis occurs between homologous chromosomes during prophase $I$ of meiosis. $(2)$ Centromeres split during anaphase $I$ of meiosis. $(3)$ Spindle fibers completely disappear during telophase of mitosis. $(4)$ Nucleoli reappear during telophase $I$ of meiosis.

$A-$ In the cell cycle,the division of a cell,$DNA$ replication,and cell growth occur.
$R-$ At the end of meiosis,there are $4$ daughter cells with a new genetic composition.

Differentiate between the Prophase of Mitosis and the Prophase of Meiosis.

Given that the average duplication time of $E. coli$ is $20$ minutes, how much time will two $E. coli$ cells take to become $32$ cells?
