Which of the following is a feature of prokaryotic cells but not eukaryotic cells?
A
Linear DNA
B
Larger cell size
C
Presence of a nucleoid region
D
Membrane-bound organelles
Verified step by step guidance1
Understand the basic differences between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler and lack a nucleus and membrane-bound organelles, while eukaryotic cells have a defined nucleus and various organelles.
Identify the key structural feature of prokaryotic cells: the nucleoid region. This is where the genetic material is located, but it is not enclosed by a membrane, unlike the nucleus in eukaryotic cells.
Recognize that prokaryotic cells typically have circular DNA, whereas eukaryotic cells have linear DNA. This is a fundamental difference in the organization of genetic material.
Consider cell size: prokaryotic cells are generally smaller than eukaryotic cells. This is due to their simpler structure and lack of organelles.
Membrane-bound organelles are a characteristic of eukaryotic cells, not prokaryotic cells. Prokaryotic cells do not have structures like mitochondria or the endoplasmic reticulum.
