Which type of cell contains DNA enclosed in a nucleus?
A
Both prokaryotic and eukaryotic cells
B
Eukaryotic cell
C
Neither prokaryotic nor eukaryotic cells
D
Prokaryotic cell
Verified step by step guidance1
Understand the difference between prokaryotic and eukaryotic cells: Prokaryotic cells lack a nucleus, and their DNA is free-floating in the cytoplasm. Eukaryotic cells, on the other hand, have a nucleus where their DNA is enclosed.
Recall that the nucleus is a membrane-bound organelle found only in eukaryotic cells. This is a defining feature of eukaryotic cells.
Eliminate incorrect options: 'Prokaryotic cell' is incorrect because prokaryotic cells do not have a nucleus. 'Neither prokaryotic nor eukaryotic cells' is incorrect because eukaryotic cells do have a nucleus.
Consider the option 'Both prokaryotic and eukaryotic cells': This is incorrect because only eukaryotic cells have DNA enclosed in a nucleus, not prokaryotic cells.
Conclude that the correct answer is 'Eukaryotic cell' because it is the only type of cell that contains DNA enclosed in a nucleus.
