$A$ phase of the cell cycle which lasts more than $95\%$ of the total duration is

$A$: The duration of the cell cycle varies in different organisms.
$R$: The duration of the cell cycle varies in different types of cells.

The rate of cleavage is inversely proportional to the duration of

Transcription process in eukaryotes occurs during < u> i and < u> ii phases of cell cycle.

If the initial amount of $DNA$ in a cell is $2C$,in which phase of the cell cycle will its amount become $4C$?

In the process of mitotic division during interphase,chromosome material remains in the form of very loosely coiled threads called
