Chromosomes with two chromatids move towards equator of spindle during

Options

A. Anaphase
B. Anaphase-I
C. Anaphase-II
D. Metaphase

Answer

To answer the question "Chromosomes with two chromatids move towards the equator of the spindle during," we need to analyze the stages of cell division, particularly mitosis. Here's a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is the process of cell division that results in two identical daughter cells. It consists of several phases: prophase, metaphase, anaphase, and telophase.

2. **Identifying Chromosome Structure**: During mitosis, chromosomes are made up of two sister chromatids, which are identical copies of the chromosome connected at a region called the centromere.

3. **Prophase**: In this initial phase, chromosomes condense and become visible, but they are not yet aligned at the equator.

4. **Metaphase**: This is the stage where chromosomes line up at the metaphase plate (the equatorial plane of the cell). During this phase, chromosomes are arranged in a line along the equator of the spindle, and each chromosome consists of two sister chromatids.

5. **Anaphase**: Following metaphase, during anaphase, the sister chromatids are pulled apart towards opposite poles of the cell. Therefore, this is not the stage where chromosomes with two chromatids are moving towards the equator.

6. **Conclusion**: Since the question specifically asks about the movement of chromosomes with two chromatids towards the equator, the correct answer is **metaphase**.

### Final Answer:
**Metaphase**
