Which of the following is a key difference between prokaryotic and eukaryotic cells?
A
Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.
B
Prokaryotic cells are generally larger than eukaryotic cells.
C
Eukaryotic cells have circular DNA, while prokaryotic cells have linear DNA.
D
Prokaryotic cells have a nucleus, while eukaryotic cells do not.
Verified step by step guidance1
Begin by understanding the basic structural differences between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler and lack membrane-bound organelles, while eukaryotic cells have complex structures with organelles such as the nucleus, mitochondria, and endoplasmic reticulum.
Consider the size difference between prokaryotic and eukaryotic cells. Generally, prokaryotic cells are smaller than eukaryotic cells, not larger. This is a common misconception.
Examine the DNA structure in both cell types. Prokaryotic cells typically have circular DNA, whereas eukaryotic cells have linear DNA organized into chromosomes within the nucleus.
Identify the presence of a nucleus. Eukaryotic cells have a defined nucleus where the DNA is stored, while prokaryotic cells do not have a nucleus; their DNA is located in a region called the nucleoid.
Review the options given in the problem and match them with the correct characteristics of prokaryotic and eukaryotic cells. The key difference is that eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.
