How is the dna in a prokaryote different from the dna in a eukaryote?
a. eukaryotes do not have alleles.
b. only prokaryotes are diploid.
c. prokaryotes do not have genes.
d. dna is in a nucleus in eukaryotes.

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.

Example - Plants and animals.
