Match the correct process of the cell cycle to its named phase.
Column A
1.
The cell separates into two new cells.:
The cell separates into two new cells.
2.
Sister chromatids separate at centromere.:
Sister chromatids separate at centromere.
3.
DNA is replicated.:
DNA is replicated.
4.
Chromosomes align in the middle of the cell.:
Chromosomes align in the middle of the
cell.
Column B
1. Cytokinesis
2. Anaphase
3. S phase
4. Metaphase
To match the correct process of the cell cycle to its named phase, we can follow these steps:
1. Identify the processes mentioned in Column A:
- The cell separates into two new cells.
- Sister chromatids separate at centromere.
- DNA is replicated.
- Chromosomes align in the middle of the cell.
2. Now let's identify the corresponding phases of the cell cycle for each process:
- The cell separates into two new cells: This process is known as cytokinesis, which occurs at the end of the cell cycle, specifically during the M phase (mitosis).
- Sister chromatids separate at centromere: This process is called chromatid separation or anaphase. It occurs during mitosis.
- DNA is replicated: This process is known as DNA replication and occurs during the S phase (synthesis phase) of the cell cycle.
- Chromosomes align in the middle of the cell: This process is called metaphase, where chromosomes align along the metaphase plate in the center of the cell. It occurs during mitosis.
So, to match the correct processes mentioned in Column A to their respective phases of the cell cycle, we have:
1. The cell separates into two new cells: Cytokinesis, which occurs in the M phase.
2. Sister chromatids separate at centromere: Anaphase, which occurs in the M phase.
3. DNA is replicated: DNA replication, which occurs in the S phase.
4. Chromosomes align in the middle of the cell: Metaphase, which occurs in the M phase.
Column B - Named Phases of the Cell Cycle:
1. Telophase - The cell separates into two new cells.
2. Anaphase - Sister chromatids separate at centromere.
3. S-phase - DNA is replicated.
4. Metaphase - Chromosomes align in the middle of the cell.
