Cells: Prokaryotic and Eukaryotic · Zoology

The genetic material in a typical prokaryotic cell is best described as:

  1. Linear DNA enclosed within a membrane-bound nucleus
  2. Circular DNA located in the nucleoid region
  3. Multiple linear chromosomes associated with histones
  4. RNA molecules dispersed throughout the cytoplasm
Show answer and explanation

Correct answer: Circular DNA located in the nucleoid region

Prokaryotic DNA is usually circular and lies in a region called the nucleoid, not surrounded by a nuclear membrane. Histone-associated linear chromosomes are characteristic of eukaryotic cells.
