• B. ds DNA virus
• C. ss RNA virus
• D. ds RNA virus

Answer 1

Answer: (C)

Genetic information is carried in viruses by either RNA or DNA. the genome of a virus can be either single stranded (ss RNA), double stranded RNA (c/sRNA), single stranded DNA E (ss DNA), double stranded DNA (ds DNA) or a mix of ss DNA and ds DNA. Retro viruses are a group of human viruses that include HIV. They are enclosed in a lipid membrane and their genetic material is the two single stranded RNA. On infection, this RNA is copied to DNA and the DNA is incorporated into the hosts chromosome.
