DNA Exists in a Concentration of Strands Known as a Nucleoid

Question

DNA exists in a concentration of strands known as a nucleoid in ________ cells.
A) eukaryotic
B) prokaryotic
C) protozoan
D) fungal

Accepted Answer

Prokaryotic cells, such as bacteria, lack a distinct nucleus and instead have a nucleoid region where their DNA is organized and concentrated. Eukaryotic cells, such as those found in animals and plants, have their DNA contained within a membrane-bound nucleus. Protozoan and fungal cells can be either eukaryotic or prokaryotic, so the answer cannot be C or D.
