Where is DNA located in a eukaryotic cell, and where is it located in a prokaryotic cell?
A
In a eukaryotic cell, DNA is in the chloroplasts; in a prokaryotic cell, it is in the cell membrane.
B
In a eukaryotic cell, DNA is in the cytoplasm; in a prokaryotic cell, it is in the nucleus.
C
In a eukaryotic cell, DNA is in the mitochondria; in a prokaryotic cell, it is in the ribosomes.
D
In a eukaryotic cell, DNA is in the nucleus; in a prokaryotic cell, it is in the nucleoid region.
Verified step by step guidance1
Understand the structure of eukaryotic and prokaryotic cells. Eukaryotic cells have membrane-bound organelles, including a nucleus, while prokaryotic cells do not.
Identify the location of DNA in eukaryotic cells. Eukaryotic cells store their DNA within the nucleus, which is a membrane-bound organelle.
Identify the location of DNA in prokaryotic cells. Prokaryotic cells do not have a nucleus; instead, their DNA is located in the nucleoid region, which is an area within the cell where the DNA is concentrated.
Eliminate incorrect options by matching the correct locations of DNA in both cell types. For example, DNA is not located in the chloroplasts or mitochondria in eukaryotic cells, nor in the cell membrane or ribosomes in prokaryotic cells.
Conclude that the correct answer is: In a eukaryotic cell, DNA is in the nucleus; in a prokaryotic cell, it is in the nucleoid region.
