The region in a bacterial cell where the DNA is concentrated is called the nucleoid. 

Structure:

• It is an irregularly shaped region within the cytoplasm 
• Unlike eukaryotic cells, this region is not enclosed by a membrane.

Explanation

The bacterial cell wall is peptidoglycan,

It is also known as murein or mucopeptide.

This complex polymer of sugars and amino acids forms a rigid, cross-linked structure

That protects the cell and is a target for antibiotics like penicillin.
