Condensation of chromosomes is completed and chromosomes are spread throughout the cytoplasm, here we are talking about which phase of the cell cycle?
1. Prophase
2. Interphase
3. Metaphase
4. Anaphase
| 1. | Pachytene | 2. | Diplotene |
| 3. | Diakinesis | 4. | Zygotene |
| Column I | Column II | ||
| (a) | pachytene | (1) | pairing of homologous chromosomes |
| (b) | metaphase I | (2) | terminalisation of chiasmata |
| (c) | diakinesis | (3) | crossing-over takes place |
| (d) | zygotene | (4) | chromosomes align at equatorial plate |
| 1. | a-3 b-4 c-2 d-1 |
| 2. | a-1 b-4 c-2 d-3 |
| 3. | a-2 b-4 c-3 d-1 |
| 4. | a-4 b-3 c-2 d-1 |
A somatic cell that has just completed the S-phase of its cell cycle, as compared to a gamete of the same species has:
| 1. | twice the number of chromosomes and twice the amount of DNA |
| 2. | the same number of chromosomes but twice the amount of DNA |
| 3. | twice the number of chromosomes and four times the amount of DNA |
| 4. | four times the number of chromosomes and twice the amount of DNA |
The microtubules from the opposite poles of the spindle attach to the pair of homologous chromosomes in
| 1. | Metaphase - I |
| 2. | Prophase - I |
| 3. | Metaphase |
| 4. | Metaphase - II |
