Which of the following statements is correct?
Correct answer: D. Some viruses use RNA as their genetic material
- A. RNA is the primary genetic material in bacteria
- B. RNA is the genetic material for all viruses
- C. DNA is the genetic material for the majority of living organisms
- D. Some viruses use RNA as their genetic material
Explanation
Some viruses use RNA as their genetic material. Viruses can contain either DNA or RNA, depending on the type. Examples of RNA viruses include the influenza virus, HIV, and SARS-CoV-2.Option A: Bacteria use RNA as their genetic material. This is incorrect because bacteria always use DNA, not RNA, as their hereditary material.Option B: All viruses use RNA as their genetic material. This is incorrect because many viruses, such as herpesvirus or adenovirus, have DNA genomes instead.Option C: DNA is the genetic material for most living organisms. While true in general, this statement does not specifically address viruses, so it does not answer the question in context.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
