Multiple Choice
In a prokaryotic cell, where is the cell's DNA primarily located?
A
In the nucleoid region of the cytoplasm (not enclosed by a membrane)
B
Packaged into multiple linear chromosomes within the endoplasmic reticulum
C
Attached to the inner membrane of the mitochondrion
D
Inside a membrane-bound nucleus
Verified step by step guidance1
Recall the structural differences between prokaryotic and eukaryotic cells, focusing on the presence or absence of membrane-bound organelles.
Understand that prokaryotic cells lack a membrane-bound nucleus, so their DNA is not enclosed within a nucleus as in eukaryotic cells.
Identify that in prokaryotes, the DNA is concentrated in a specific region of the cytoplasm called the nucleoid, which is not surrounded by a membrane.
Recognize that prokaryotic DNA is typically a single circular chromosome, unlike the multiple linear chromosomes found in eukaryotes.
Conclude that the correct location of DNA in a prokaryotic cell is the nucleoid region of the cytoplasm, not inside membrane-bound organelles like the nucleus, mitochondria, or endoplasmic reticulum.
