Questions and Answers

What is the main difference between the structure of DNA in prokaryotes and eukaryotes?

Prokaryotic DNA is circular, whereas eukaryotic DNA is linear.

Where is the DNA found in prokaryotic cells, and what is it associated with?

The DNA is found in the cytoplasm (nucleoid) and is not associated with histones.

What is unique about the genes found in eukaryotic DNA compared to prokaryotic DNA?

Eukaryotic genes contain introns.

How do the DNA molecules of mitochondria and chloroplasts compare to prokaryotic DNA?
