Question

which statement accurately contrasts the genetic material of prokaryotic cells with that of eukaryotic cells as described in the source material? prokaryotic dna is located in a membrane - bound nucleus, while eukaryotic dna floats freely in the cytoplasm. prokaryotes have multiple linear chromosomes, whereas eukaryotes typically have a single circular chromosome. prokaryotic dna is a single circular chromosome in the nucleoid, while eukaryotic dna is organized into multiple linear chromosomes within a nucleus. both prokaryotes and eukaryotes organize their dna into chromatin by wrapping it around proteins.

Explanation:

• Prokaryotic cells lack a membrane - bound nucleus. Their DNA is in the nucleoid region and is a single circular chromosome.
• Eukaryotic cells have a nucleus. Their DNA is organized into multiple linear chromosomes within the nucleus.
• Option 1 is incorrect because prokaryotic DNA is not in a membrane - bound nucleus and eukaryotic DNA is in the nucleus.
• Option 2 is incorrect as prokaryotes have a single circular chromosome and eukaryotes have multiple linear chromosomes.
• Option 4 is incorrect as prokaryotes do not wrap their DNA around proteins to form chromatin in the same way as eukaryotes.

Answer:

Prokaryotic DNA is a single circular chromosome in the nucleoid, while eukaryotic DNA is organized into multiple linear chromosomes within a nucleus.
