What is the name given to the undefined nuclear region of prokaryotic cell?

Explanation

**Step-by-Step Solution:**

1. **Understanding Prokaryotic Cells**: Prokaryotic cells are simple, single-celled organisms that lack a defined nucleus. They are found in primitive organisms such as bacteria.

2. **Identifying the Nuclear Region**: In prokaryotic cells, the genetic material (DNA) is not enclosed within a membrane-bound nucleus. Instead, it is found in a region of the cell that is not clearly defined or separated from the cytoplasm.

3. **Characteristics of the Nuclear Region**: This undefined nuclear region contains the genetic material in a scattered form. There is no nuclear membrane, and the genetic material is often found in a dense area within the cell.
