phase from G1 phase?
When a cell is viewed under the microscope, it does
not show golgi complex, endoplasmic reticulum,
nucleolus, nuclear envelope in which stage of cell
division?
| 1. | Early prophase |
| 2. | Late prophase |
| 3. | Interphase |
| 4. | Telophase |
These given statements are related with specific phase of meiosis, select the unrelated statement with the phase given below.
| Statement | Phase | ||
| 1. | The homologous chromosome separate, while sisterchromatids remain associated at their centromere |
– | Anaphase I |
| 2. | he bivalent chromosomes align on the equatorial plate | – | Metaphase I |
| 3. | Cytokinesis follows resulting in the formation of tetrad of cells | – | Telophase I |
| 4. | Terminalisation of chiasmata of prophase | – | Final stage |
During what phase in the cell cycle would you find the most DNA per cell?
1. G1
2. G2
3. S
4. Prophase II
“The synaptonemal complex is formed during _A_
stage and dissolves during _B_ stage”.
Complete the above statement by choosing the correct
option for A and B
| A | B | |
| 1. | Diplotene | Diakinesis |
| 2. | Leptotene | Zygotene |
| 3. | Zygotene | Diplotene |
| 4. | Pachytene | Diplotene |
Major event that occurs during anaphase of mitosis which brings about equal distribution of chromosomes is:
| 1. | Condensation of chromatin |
| 2. | Replication of genetic material |
| 3. | Splitting of centromere |
| 4. | Pairing of homologous chromosomes |
