Question

how is the dna in a prokaryote different from the dna in a eukaryote?
a. eukaryotes do not have chromosomes.
b. they have different numbers of chromosomes.
c. only prokaryotes are haploid.
d. dna in eukaryotes is located in the nucleus.

Explanation:

• Option A is incorrect: Eukaryotes do have linear chromosomes.
• Option B is incorrect: While chromosome counts vary, this is not a defining structural difference between prokaryotic and eukaryotic DNA.
• Option C is incorrect: Some eukaryotic cells (like gametes) are haploid, so this is not unique to prokaryotes.
• Option D is correct: Prokaryotes lack a membrane-bound nucleus, so their DNA is in the cytoplasm (nucleoid region), while eukaryotic DNA is enclosed in the nucleus.

Answer:

D. DNA in eukaryotes is located in the nucleus.
