II: | The cell is metabolically active and grows continuously |
III: | Cell replicates its DNA |
1. | Only II | 2. | I and II only |
3. | Only I | 4. | I, II and III |
What would be the DNA content and chromosome number in a cell at the end of S phase with 2C DNA content and 2N chromosome number in G1?
1. | 4C and 4N | 2. | 2C and 4N |
3. | 4C and 2N | 4. | 2C and 2N |
Proteins are synthesized in preparation for mitosis during:
1. | G1 phase | 2. | S phase |
3. | G2 phase | 4. | M phase |
I: | A-Interphase; B-G1 phase; C-S phase; D-G2 phase |
II: | P-Prophase; Q- Anaphase; R-Metaphase; S- Diakinesis |
III: | X-Karyokinesis; Y- Cytokinesis |
1. | Only III | 2. | Only I and III |
3. | Only II | 4. | I, II and III |
The cells in the quiescent stage [G0] phase of the cell cycle:
1. | exit from the S phase |
2. | continue the events of cell cycle and complete the division |
3. | are metabolically active |
4. | cannot ever proliferate |
The phase of the cell cycle during which DNA replication takes place is:
1. | G1 phase | 2. | S phase |
3. | G2 phase | 4. | M phase |

3. | 16, 16, 8 | 4. | 16, 16, 16 |
The Mitotic phase of a typical eukaryotic cell is divided into:
