Question

question 2 of 15
how does the dna of prokaryotic cells differ from the dna of eukaryotic cells?
○ prokaryotic dna is protected by a cell membrane, whereas eukaryotic dna is protected by a cell wall.
○ prokaryotic dna has a linear structure, whereas eukaryotic dna has a circular, closed - loop structure.
○ prokaryotic dna is bound by an organelle, whereas eukaryotic dna is free floating in the cytoplasm.
○ prokaryotic dna is contained in the cytoplasm, whereas eukaryotic dna is contained in the nucleus.
○ prokaryotic dna is composed of four nucleotides, whereas eukaryotic dna is composed of five nucleotides.

Explanation:

Prokaryotes lack a membrane-bound nucleus, so their DNA floats freely in the cytoplasm. Eukaryotes have a nucleus that encloses their genetic material, separating it from the cytoplasm. Other options are incorrect: prokaryotic DNA is circular (not linear), eukaryotic DNA is linear; cell membranes/walls protect cells, not directly DNA; both use 4 nucleotides.

Answer:

Prokaryotic DNA is contained in the cytoplasm, whereas eukaryotic DNA is contained in the nucleus.
