Answer #1

a. Nuclear membrane is composed of DNA.- In eukaryotes the nuclear membrane is composed of two lipid bilayer membranes.

b. Prokaryotes do not contain nucleolus. Right.

They do not have any membrane-bound organelles like eukaryotes, so they do not possess a nucleus. But their genetic material is [resent in the region inside the cytoplasm called the nucleoid.

c. Prokaryotes do not contain ribosomes. Ribosomes are found in both, prokaryotes and eukaryotes.

d. All viruses have RNA genomes.- Some viruses like Human papillomavirus (HPV), and possibly some adenoviruses.
