Question: prokaryotic and eukaryotic cells have structurally similar dna?
Answer: The nucleus holds the eukaryotic cell's DNA. Prokaryotic cells do not have a nucleus; rather, they have a membraneless nucleoid region (open part of the cell) that holds free-floating DNA, according to Washington University. ... Ribosomes: In eukaryotic cells, the ribosomes are bigger, more complex and bound by a membrane.
