Answer: The correct answer is D) DNA is in a nucleus in eukaryotes.
Prokaryotes are those organisms that lack a well defined nucleus and membrane bound subcellular organelles (like endoplasmic reticulum, golgi complex, mitochondria). The genetic material lies in the cytoplasm of the cell in these organisms.
Example - Bacteria like E.coli.
On the other hand, eukaryotes are those organisms that contain a well defined nucleus that possesses the genetic material (DNA). These organisms also contain membrane bound subcellular organelles.
<u>The DNA (Deoxyribose nucleic acid) of the eukaryotes is different from that of prokaryotic DNA based on their nuclear structure, a number of a chromosome, their binding protein, and selective permeability.</u>
