In most prokaryotic cells, where is the cell’s DNA primarily located?
A
Packaged into histone-bound chromosomes inside the nucleolus
B
Inside a membrane-bound nucleus
C
Only within mitochondria and chloroplasts
D
In the nucleoid region within the cytoplasm (not enclosed by a membrane)
Verified step by step guidance1
Understand the structural differences between prokaryotic and eukaryotic cells, focusing on the presence or absence of membrane-bound organelles.
Recall that prokaryotic cells lack a membrane-bound nucleus, which is a defining feature of eukaryotic cells.
Identify that in prokaryotes, DNA is not enclosed within a nucleus but is instead found in a specific region called the nucleoid.
Recognize that the nucleoid is an irregularly-shaped region within the cytoplasm where the cell's DNA is concentrated, but it is not surrounded by a membrane.
Conclude that the cell's DNA in prokaryotes is primarily located in the nucleoid region within the cytoplasm, distinguishing it from eukaryotic cells where DNA is inside a membrane-bound nucleus.
