E)linear and tightly wrapped around histone proteins

Question

Quizplus · Accepted Answer

The prokaryotic chromosome is not held within a membrane-bound nucleus, unlike the eukaryotic chromosomes. Instead, it is localized to a nucleoid region, where the DNA is loosely packed and not bound to histone proteins. The prokaryotic chromosome is also typically circular, unlike the linear chromosomes found in eukaryotes. Therefore, the best choice is B. Single-stranded DNA is also not characteristic of the prokaryotic chromosome.
