Kinetochores are not

 

1.      Formed by spindle Fibres

 

2.      Formed by asters

 

3.      Help in the attachment of chromosomes to the spindle Fibres

 

4.     Disc-shaped structure

All the chromosomes coming to lie at the equator with one chromatids of each chromosome connected by it's kinetochore to spindle Fibres from one pole and it's sister chromatids connected by it's kintetochore to spindle Fibres from the opposite poles.

This is a characteristic features of which of the following phases?

1.      Prophase

2.      Metaphase

3.      Anaphase

4.     Telophase

The plane of alignment of chromosomes at metaphase is referred to as

1.      Metaphase line

2.      Metaphase plate

3.      Metaphase area

4.     Metaphase shape

The two daughter chromatids start moving towards the two opposite poles, this is a characteristic feature of

1. Prophase

2. Metaphase

3. Anaphase

4. Telophase

The leading edge of chromosomes in the Anaphase stage is

1.     Centromere

2.      Two arms

3.      Only one arm

4.     Kinetochore

Splitting of centromere occurs in

1.      Anaphase

2.      Metaphase

3.      Telophase

4.     Prophase

The reformation of the nuclear envelope, nucleolus, Golgi complex, and ER occurs in

1.      Prophase

2.      Metaphase

3.      Anaphase

4.     Telophase

The end of which of the following mark's completion of Mitosis?

1. Cytokinesis

2. Karyokinesis

3. Interkinesis

4. Telophase

The furrow gradually deepens and ultimately joins in the centre dividing the cell cytoplasm into two. Here, the cell is

(1) Animal cell

(2) Plant cell

(3) Both A and B

(4) Only Root tip cells

The Cytokinesis of plant cell is not same as that of animal cell because of

1.      Inextensible cell wall

2.      Cell membrane differences

3.      Intermediate Filaments

4.     Nuclear envelope
