Question

Following are the stages of cell division :
A. Gap 2 phase
B. Cytokinesis
C. Synthesis phase
D. Karyokinesis
E. Gap 1 phase
Choose the correct sequence of stages from the options given below

• A. C-E-D-A-B
• B. E-B-D-A-C
• C. B-D-E-A-C
• D. E-C-A-D-B

Answer 1

The Correct Option is D

To understand the correct sequence of cell division stages, we need to focus on the phases of the cell cycle. The cell cycle consists of interphase and the mitotic phase. Interphase includes the stages where the cell prepares for division.

1. Gap 1 phase (G1): This is the first stage after cell division where the cell grows and carries out normal functions. It prepares for the synthesis phase.
2. Synthesis phase (S): In this stage, DNA replication occurs, and the cell's genetic material is duplicated.
3. Gap 2 phase (G2): Here, the cell continues to grow and prepares for mitosis. It checks for DNA replication errors.
4. Karyokinesis (M): This is the stage of mitosis where the nucleus divides. It involves prophase, metaphase, anaphase, and telophase.
5. Cytokinesis: This is the last step where the cytoplasm divides, resulting in two daughter cells.

Given the sequence options, the correct sequence from these stages is:
- Gap 1 phase (E)
- Synthesis phase (C)
- Gap 2 phase (A)
- Karyokinesis (D)
- Cytokinesis (B)
The correct sequence is E-C-A-D-B.

Answer 2

The correct sequence of stages in cell division is:
E. Gap 1 phase, where the cell grows.
C. Synthesis phase, where DNA replication occurs.
A. Gap 2 phase, where the cell continues to grow and prepare for division.
D. Karyokinesis, where the nucleus divides.
B. Cytokinesis, where the cytoplasm divides, completing the process.
 

Thus, the correct answer is (4) E-C-A-D-B.
