Prokaryotic cells lack a membrane-bound nucleus. Their genetic material must therefore be housed differently.

Where is the genetic material located in a prokaryotic cell?

Inside the mitochondria

Inside a true nucleus bounded by a nuclear membrane

Distributed evenly throughout the cytoplasm with no defined region

In a region of the cytoplasm called the nucleoid

Correct Answer

In a region of the cytoplasm called the nucleoid

Explanation

In prokaryotic cells, genetic material is concentrated in a region of the cytoplasm called the nucleoid. Unlike the eukaryotic nucleus, the nucleoid has no surrounding membrane - the DNA is simply coiled and compacted in this region of the cytoplasm. Prokaryotes typically have a single circular chromosome.
