Select the correct option with respect to mitosis.
 

1.	Chromatids start moving towards opposite poles in telophase.
2.	Golgi complex and endoplasmic reticulum are still visible at the end of prophase.
3.	Chromosomes move to the spindle equator and get aligned along the equatorial plate in metaphase.
4.	Chromatids separate but remain in the center of the cell in anaphase.

During mitosis ER and nucleolus begin to disappear at:

Which stages of cell division do the following figures A and B represent respectively? 

Given below is a schematic break-up of the phases/stages of cell cycle-
   
Which one of the following is the correct indication of the stage/phase in the cell cycle?

Synapsis occurs between:

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

During gamete formation, the enzyme recombinase participates during:
1. Metaphase-I
2. Anaphase-II
3. Prophase-I
4. Prophase-II

The complex formed by a pair of synapsed homologous chromosomes is called:

1. Kinetochore

2. Bivalent

3. Axoneme

4. Equatorial plate

The enzyme recombinase is required at which stage of meiosis:
