• smooth endoplasmic reticulum

Which statement best describes the difference between prokaryotes and eukaryotes with regard to DNA?

• Prokaryotic DNA is helical, while eukaryotic DNA is circular.

• Prokaryotic DNA is circular, while eukaryotic DNA is helical.

• Prokaryotic DNA is single stranded, while eukaryotic DNA is triple stranded.
