The binary fission method of asexual reproduction starts with the splitting of the ________ of the parent cell.

Options

A. Nucleus
B. Chromosomes
C. Nucleolus
D. Gene

Explanation

**Step-by-Step Solution:**

1. **Understanding Binary Fission**: Binary fission is a method of asexual reproduction commonly seen in unicellular organisms, such as bacteria. It involves the division of a single parent cell into two identical daughter cells.

2. **Identifying the Starting Point**: The process of binary fission begins with the splitting of a specific part of the parent cell. In this case, we need to identify which part that is.

3. **Role of the Nucleus**: In binary fission, the first step involves the division of the nucleus of the parent cell. The nucleus contains the genetic material (DNA) that is essential for the formation of new cells.

4. **Mitosis Process**: During binary fission, mitosis occurs, which is the process of cell division that ensures that the genetic material is accurately copied and distributed to the daughter cells.

5. **Resulting Daughter Cells**: After the nucleus divides, the rest of the cell follows, leading to the formation of two genetically identical daughter cells. These daughter cells are clones of the parent cell.

6. **Conclusion**: Therefore, the binary fission method of asexual reproduction starts with the splitting of the **nucleus** of the parent cell.

**Final Answer**: The binary fission method of asexual reproduction starts with the splitting of the **nucleus** of the parent cell.
