Q. No.A stage in cell division is shown in the figure. Select the answer which gives the correct identification of the stage with its characteristics:
|
1. |
Late anaphase |
Chromosomes move away from the equatorial plate, Golgi complex not present |
|
2. |
Cytokinesis |
Cell plate formed, mitochondria distributed between two daughter cells |
|
3. |
Telophase |
Endoplasmic reticulum and nucleolus not reformed yet |
|
4. |
Telophase |
Nuclear envelop reforms, Golgi complex reforms |
| 1. | kinetochore |
| 2. | both centromere and kinetochore |
| 3. | centromere, kinetochore and areas adjoining centromere |
| 4. | centromere |
| 1. | Metaphase-spindle fibers attached to kinetochores, centromeres split and chromatids separate |
| 2. | Metaphase- chromosomes moved to spindle equator, chromosomes made up of two sister chromatids |
| 3. | Anaphase - centromeres split and chromatids separate and start moving away |
| 4. | Late prophase - chromosomes move to spindle equator |
Identify the meiotic stage in which the homologous chromosomes separate while the sister chromatids remain associated at their centromeres.
1. Metaphase-II
2. Anaphase-I
3. Anaphase-II
4. Metaphase-I
| 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. |
At metaphase, chromosomes are attached to the spindle fibres by their:
1. Centromere
2. Satellites
3. Secondary constrictions
4. Kinetochores
During mitosis ER and nucleolus begin to disappear at:
1. late prophase
2. early metaphase
3. late metaphase
4. early prophase
Which stages of cell division do the following figures A and B represent respectively?
| 1. | Metaphase- Telophase | 2. | Telophase- Metaphase |
| 3. | Late anaphase- Prophase | 4. | Prophase- Anaphase |
