Cell Cycle Biology Test Series for NEET-2020

Test Preparation on Cell cycle - Biology Test Series for NEET - 2020

1.

Which one of the following is the correct indication of the
stage/phase in the cell cycle

1B – Metaphase
2C – Karyokinesis
3D – Synthetic phase
4A – Cytokinesis

2.

Condensation of chromosomes occurs in

1Prophase I
2Prophase II
3Anaphase
4Metaphase

(a) Condensation of chromosomes occurs in the prophase-
I. After that chromosome moves toward the poles.

3.

1A and B are correct
2B and D are correct
3B and E are correct
4B and C are correct

4.

The role of meiosis

1Formation of gametes
2Bringing haplophase
3Bringing diplophase
4Completing life cycle

(b) The most important role of meiosis is to maintain
haploid phase.

5.

Which stage connecting link between Meiosis I and Meiosis II

1Interphase I
2Interphase II
3Interkinesis
4Anaphase I

6.

Spindle apparatus is formed during which stage of mitosis

1Metaphase
2Prophase
3Interphase
4Anaphase

(a) Colchicine is obtained from colchicum autumnale plant,
which inhibits the formation of spindle fibers in
metaphase.

7.

Diploid living organism develops from zygote by repeated
cell divisions is called

1Glycolysis
2Cyclosis
3Haemolysis
4Mitosis

(d) Cyclin is a protein, which participates in cell division.

8.

Synaptonemal complex is formed during

1Meiosis
2Amitosis
3Mitosis
4Cytokinesis

(a) Synaptonemal complex is formed during meiotic
prophase first.

9.

Recombinant nodules are found during which of the
following

1Anaphase
2Prophase
3Telophase
4Metaphase

(b) Knot like structure ‘Chromomeres’ found in the stage
leptotene of prophase first of meiosis.
