D
In the Golgi apparatus
Guida verificata passo dopo passo1
Understand the basic cell structure differences between prokaryotes and eukaryotes. Prokaryotes lack membrane-bound organelles such as a nucleus.
Recall that in eukaryotic cells, DNA is enclosed within a membrane-bound nucleus, but prokaryotes do not have this structure.
Identify that in prokaryotes, DNA is found in a specific region of the cytoplasm called the nucleoid, which is not enclosed by a membrane.
Recognize that mitochondria and Golgi apparatus are membrane-bound organelles found in eukaryotic cells, not prokaryotes.
Conclude that the primary location of DNA in most prokaryotes is the nucleoid region of the cytoplasm, which is not membrane-bound.
