Genetic material that is single stranded and made with a ribose sugar.

• DNA

• RNA

Eukaryotic DNA is...

• Double stranded and circular

• Single stranded and circular

• Double stranded and linear

• Single stranded and linear

Answer explanation

Eukaryotes have multiple linear DNA strands while prokaryotes have a single circular DNA strand.

DNA is traditionally double stranded.

Small, extra chromosomal, double stranded, circular DNA molecule.

• DNA

• PLASMID

• RNA

• ENZYME

Both prokaryotic and eukaryotic cells have plasmids?

• True

• False

Answer explanation

Although traditionally discussed in prokaryotes, plasmids have been found in eukaryotes.

Plasmids carry a minimum of one gene that is beneficial to the host but do not carry genetic information about the organism.
