Which of the following nucleic acids is present in an organism having 70S ribosomes only?

1. Double stranded circular DNA with histone proteins
2. Single stranded DNA with protein
3. Double stranded circular naked DNA
4. Double stranded DNA enclosed in nuclear membrane

Correct answer: Double stranded circular naked DNA

Solution

Organisms with only 70S ribosomes are prokaryotes, which lack a nuclear membrane and histone-bound chromosomes. Their genetic material is typically double-stranded, circular, and naked DNA.
