During cell cycle, events are under

1. Genetic control

2. Metabolic control

3. Cytoplasmic control

4. Mitochondrial control

Initiation of the assembly of mitotic spindle and the complete disintegration of the nuclear envelope can be observed in respectively

1.  Prophase and anaphase I.

2.  Metaphase and telophase.

3.  Prophase and metaphase.

4.  Metaphase and metaphase-I.

Match the following column I with column II. 

1. A-(ii) B-(i) C-(iii) D-(iv)

2. A-(ii) B-(iii) C-(v) D-(iv)

3. A-(i) B-(ii) C-(v) D-(iv)

4. A-(ii) B-(iii) C-(iv) D-(v)

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.

Options :
         I    II    III    IV

1.      T    F     F      F

2.      F    T     T     T

3.      F    F     T     T

4.      T    F     F     T

The microtubules from the opposite poles of the spindle attach to the pair of homologous chromosomes in

1. Metaphase - I 

2. Prophase - I

3. Metaphase 

4. Metaphase - II

Which of the following stages of Meiosis I of Prophase I is not correctly matched with events occurring during that stage?

Cells in ${\mathrm{G}}_0$ phase:
1. terminate the cell cycle
2. exit the cell cycle
3. enter the cell cycle
4. suspend the cell cycle

The correct sequence of phases in cell cycle is:

1. ${\mathrm{G}}_1\to \mathrm{S}\to {\mathrm{G}}_2\to \mathrm{M}$

2. $\mathrm{M}\to {\mathrm{G}}_1\to {\mathrm{G}}_2\to \mathrm{S}$

3. ${\mathrm{G}}_1\to {\mathrm{G}}_2\to \mathrm{S}\to \mathrm{M}$

4. $\mathrm{S}\to {\mathrm{G}}_1\to {\mathrm{G}}_2\to \mathrm{M}$
