Cell Cycle: Overview
This topic covers concepts such as Cell Growth, DNA Replication, Kinetochores, Chromatids, Cell Cycle and Cell Division, Cell Cycle, Phases of Cell Cycle, Interphase, G1 Phase, S Phase, G2 Phase, M Phase, G0 Phase and Cell Division.
Important Questions on Cell Cycle

In which phase of the cell cycle, cytokinesis takes place.
A bacterial culture was started with an inoculum of cells. What will be the number of cells at the end of cycles of division, assuming that every progeny cell undergoes division in each cycle?
Assertion (A) : Chromosomes are inactive and not transcribed to messenger RNA in phase of apparent division
Reason (R): Cells remains metabolically active but no longer divide in quiescent stage
Duplication of can occur at which phase?
Cell division is a continuous process.
At what phase of cell cycle the grown up cell divides? (Mitotic / Interphase)
If a cell has twice as much DNA as in a normal functional cell, it means that the cell:
It is said that the one cycle of cell division in human cells (eukaryotic cells) takes 24 hours. Which phase of the cycle, do you think occupies the maximum part of the cell cycle, whether it is M phase or interphase?
