Prepare for NEET Biology Cell Cycle and Cell Division with MCQs & PYQs on NEET.GUIDE. Access free practice, previous year questions, and expert help for mitosis and meiosis understanding.
Given below are two statements:
Statement I: During phase of cell cycle, the cell is metabolically inactive.
Statement II: The centrosome undergoes duplication during S phase of interphase.
In the light of the above statements, choose the most appropriate answer from the options given below:
Both Statement I and Statement II are correct
Both Statement I and Statement II are incorrect
Statement I is correct but Statement II is incorrect
Statement I is incorrect but Statement II is correct
Which of the following statements regarding the cell cycle is INCORRECT?
The G1 checkpoint ensures the cell is ready to proceed to DNA replication.
DNA replication occurs during the G2 phase of interphase.
Mitosis includes the stages of prophase, metaphase, anaphase, and telophase.
Cells can exit the cell cycle and enter a non-dividing state called G0.
During which phase of the cell cycle does centrosome duplication occur?
phase
S phase
phase
M phase

Choose the correct statements regarding cell cycle
I. Interphase is called the resting phase
II. Interphase is the time during which the cell is preparing for division
III. The interphase is divided into phases, i.e.,G_1, S and G_2-phase
IV. Interphase represents the phase between the two successive M-phases

The interphase is divided into three main phases. There phases are
-phase, M-phase and -phase
M-phase, S-phase and divisional phase
Gap 1 phase, synthesis phase and gap 2 phase
M-phase -phase and divisional phase
