Which chromosome may lost during cell division:

Options

A. Giant chromosome
B. Acentric chromosome
C. Polycentric chromosome
D. Telocentric chromosome

Answer

**Step-by-Step Solution:**

1. **Understanding Chromosomes**: First, we need to understand what chromosomes are. Chromosomes are structures within cells that contain DNA and proteins. They are crucial for cell division and genetic inheritance.

2. **Types of Chromosomes**: There are various types of chromosomes, including:
- **Giant Chromosomes**: These are large chromosomes that can be seen under a light microscope during certain stages of cell division.
- **Acentric Chromosomes**: These chromosomes lack a centromere, which is the region where the spindle fibers attach during cell division.
- **Polycentric Chromosomes**: These chromosomes have multiple centromeres.
- **Telocentric Chromosomes**: These chromosomes have the centromere located at one end.

3. **Focus on Acentric Chromosomes**: The question specifically asks which chromosome may be lost during cell division. Acentric chromosomes are unique because they do not have a centromere.

4. **Mechanism of Cell Division**: During cell division, particularly in the anaphase stage, spindle fibers pull chromosomes apart towards opposite poles of the cell. Acentric chromosomes do not have a centromere for the spindle fibers to attach to.

5. **Consequences of Acentric Chromosomes**: Since spindle fibers cannot attach to acentric chromosomes, they cannot be pulled to either pole during cell division. As a result, these chromosomes may be lost in the daughter cells.

6. **Conclusion**: Based on the above reasoning, the chromosome that may be lost during cell division is the acentric chromosome.

**Final Answer**: Acentric chromosome.
