The complete disintegration of the nuclear envelope marks the
1. Ending of the second phase(stage) of mitosis
2. Start of the second phase(stage) of mitosis
4. Both B and C
Condensation of chromosomes is completed and chromosomes are spread throughout cytoplasm, here we are talking about which phase of cell cycle?
The stage at which morphology of chromosomes is studied very easily would be
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?
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
The leading edge of chromosomes in the Anaphase stage is
2. Two arms
3. Only one arm
Splitting of centromere occurs in
The reformation of the nuclear envelope, nucleolus, Golgi complex, and ER occurs in
