The correct sequence of phases in cell cycle is:
Cells in phase:
1. terminate the cell cycle
2. exit the cell cycle
3. enter the cell cycle
4. suspend the cell cycle
The microtubules from the opposite poles of the spindle attach to the pair of homologous chromosomes in
1. Metaphase - I
2. Prophase - I
4. Metaphase - II
Consider the following four statements (I- IV) related to cell cycle, and select the correct option stating them as true (T) and false (F)
I. Cell growth in terms of cytoplasmic increase is a continuous process.
II. Interphase is the phase of actual cell division.
III. The number of chromosomes doubles in S-phase.
IV. The cell that does not divide further exits G1-phase to enter a metabolically inactive stage.
I II III IV
