Bacterial chromosomes:

Question

Quizplus · Accepted Answer

Bacterial chromosomes are not organized into discrete chromosomes with individual membranes like eukaryotes. Instead, the DNA is highly condensed and packed into a region called the nucleoid, which is present in the cytoplasm of the cell. Therefore, option A is correct as bacterial chromosomes are highly compacted into structures called nucleoids. Option B is incorrect as the "beads on a string" appearance refers to eukaryotic chromatin, not bacterial chromosomes. Option C is incorrect as bacteria lack a nuclear membrane. Option D is incorrect as nucleosomes are structures made up of DNA and histone proteins, which are characteristic of eukaryotic chromatin, not bacterial chromosomes. Option E is incorrect as bacterial chromosomes are much shorter than the bacterium's cell body and are not fully extended in the same way that eukaryotic chromosomes can be.
