In prokaryotic cells, DNA congregates in an area called theMultiple choice question.capsule.nucleoid.cell wall.ribosome.

Step 1: Break Down the Problem

We need to identify the correct term that describes the area in prokaryotic cells where DNA is concentrated. We will examine each of the options provided.

Step 2: Relevant Concepts

In prokaryotic cells, the genetic material is not enclosed in a nucleus like in eukaryotic cells. Instead, it is located in a region called the nucleoid.

Step 3: Analysis and Detail

1. Capsule: This is a protective layer that surrounds some bacteria. It’s not involved in storing DNA.
2. Nucleoid: This is the correct term. It refers specifically to the region in prokaryotic cells where the circular DNA is located.
3. Cell Wall: This provides structure and protection to the cell but does not hold DNA.
4. Ribosome: These are the sites of protein synthesis within the cell and do not contain DNA.

Step 4: Verify and Summarize

The nucleoid is the region where prokaryotic cells keep their genetic material. Unlike eukaryotes, they do not possess a defined nucleus, and the nucleoid serves this function.

Final Answer

The correct answer is nucleoid.
