The genetic material of a bacterial cell is localized within a discrete region called as

Options

A. Nucleus
B. Nucleolus
C. Plasmid
D. Nucleoid

Answer

**Step-by-Step Solution:**

1. **Understanding Bacterial Cells**: Bacterial cells are classified as prokaryotic cells, which means they lack a defined nucleus. This is a key characteristic that differentiates them from eukaryotic cells.

2. **Identifying the Region for Genetic Material**: In bacterial cells, the genetic material (DNA) is not enclosed within a membrane-bound nucleus. Instead, it is found in a specific area within the cell.

3. **Defining the Discrete Region**: The region where the genetic material is localized in bacterial cells is known as the "nucleoid." The term "nucleoid" suggests a nucleus-like structure, but it is important to note that it does not have a nuclear membrane.

4. **Characteristics of the Nucleoid**: The nucleoid is an irregularly shaped region that contains all or most of the genetic material of the bacterial cell. Unlike the nucleus in eukaryotic cells, the nucleoid is not surrounded by a membrane.

5. **Final Answer**: Therefore, the genetic material of a bacterial cell is localized within a discrete region called the nucleoid.
