At anaphase -II of meiosis each chromosome contains:-

Options

A. 4 DNA
B. 3- DNA
C. 2- DNA
D. 1- DNA

Answer

To answer the question "At anaphase -II of meiosis each chromosome contains:", we need to understand the process of meiosis, particularly focusing on anaphase II.

### Step-by-Step Solution:

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells from one diploid cell. It consists of two rounds of division: meiosis I and meiosis II.

2. **Stages of Meiosis**:
- **Meiosis I**: This is a reductional division where homologous chromosomes are separated. At the end of meiosis I, each daughter cell has half the number of chromosomes, but each chromosome still consists of two sister chromatids.
- **Meiosis II**: This is similar to mitosis, where the sister chromatids of each chromosome are separated.

3. **Anaphase II**: During anaphase II, the sister chromatids of each chromosome are pulled apart towards opposite poles of the cell. At this stage, each chromosome is no longer in the form of a bivalent (two homologous chromosomes) but as individual chromatids.

4. **Chromosome Composition**:
- Each chromosome at anaphase II consists of one chromatid.
- Since meiosis is a reduction division, the number of chromosomes is halved, and each chromosome is now haploid (N).

5. **Conclusion**: Therefore, at anaphase II of meiosis, each chromosome contains one DNA molecule, which corresponds to the haploid condition (N).

### Final Answer:
At anaphase II of meiosis, each chromosome contains **haploid DNA (N)**, specifically **1 DNA** molecule.
