Expert Solution
Step 1

Prokaryotic DNA is double-stranded circular DNA that is dispersed in the nucleoid, a dense area of cytoplasm. In prokaryotes, the DNA is not surrounded by a nuclear membrane. A single chromosome is represented by a single circular DNA strand. Because there are no histone proteins in this DNA, it is not a supercoiled shape like that found in eukaryotes. They use nucleoid-associated proteins to create loops. Prokaryotic DNA is commonly referred to as "bare DNA" since it lacks the histone framework. In eukaryotes, DNA is found in the nucleus, which is surrounded by the nuclear membrane. It has a straight form.
