The structure that contains the genetic information in a bacterial cell is called the :
(a) nucleus
(b) nucleoid
(c) nucleolus
(d) nucleosome

Options

A. nucleus
B. nucleoid
C. nucleolus
D. nucleosome

Explanation

To solve the question regarding the structure that contains genetic information in a bacterial cell, we can follow these steps:

### Step 1: Understand the Types of Organisms
Bacteria are classified as prokaryotic organisms. Prokaryotes are characterized by the absence of a defined nucleus.

**Hint:** Remember that prokaryotic cells do not have a true nucleus.

### Step 2: Identify the Genetic Material in Prokaryotes
In prokaryotic cells, the genetic material is not enclosed within a membrane-bound nucleus. Instead, it is found in a region of the cell called the nucleoid.

**Hint:** Look for terms that refer to the genetic material in prokaryotes.

### Step 3: Analyze the Options
- **(a) Nucleus:** This is not correct, as prokaryotes do not have a nucleus.
- **(b) Nucleoid:** This is the correct answer, as it refers to the region where the genetic material is located in bacterial cells.
- **(c) Nucleolus:** This is found in eukaryotic cells and is not present in bacteria.
- **(d) Nucleosome:** This structure is associated with eukaryotic DNA packaging and is not relevant to prokaryotes.

**Hint:** Eliminate options that are not applicable to prokaryotic cells.

### Step 4: Conclusion
Based on the analysis, the correct answer to the question is (b) nucleoid.

**Final Answer:** (b) nucleoid
