Mitosis is characterised by

Options

A. 1. reduction division
B. 2.equal division
C. 3. both reduction and equal division
D. 4. none of the above

Answer

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two daughter cells, each having the same number and type of chromosomes as the parent cell. This process is crucial for growth, repair, and asexual reproduction in organisms.

2. **Chromosome Replication**: Before mitosis begins, the cell undergoes DNA replication during the S phase of the cell cycle. This results in duplicated chromosomes, which are composed of two sister chromatids.

3. **Distribution of Chromosomes**: During mitosis, the replicated chromosomes are aligned and then separated into two new nuclei. This ensures that each daughter cell receives an identical set of chromosomes.

4. **Types of Division**: Mitosis is characterized as an "equational division" because the number of chromosomes remains the same before and after the division. This means that if a parent cell has a diploid number of chromosomes, each daughter cell will also have the same diploid number.

5. **Conclusion**: Therefore, the correct characterization of mitosis is "equal division," as it produces daughter cells that are genetically identical to the parent cell.

### Final Answer:
Mitosis is characterized by **equal division**.
