Which of the following statements explains why viruses are only able to multiply in living cells?
Correct answer: B. Virus do not possess the necessary components for self-replication.
- A. Their binary fission is controlled by host cell genes.
- B. Virus do not possess the necessary components for self-replication.
- C. DNA is only able to replicate inside living cells
- D. They have only enough genetic information for DNA replication.
Explanation
Viruses can only multiply inside living cells because they lack the cellular machinery and enzymes needed to reproduce on their own. They depend entirely on host cells to provide the tools for replication, protein synthesis, and assembly of new viral particles. Other options are either factually incorrect or misleading.

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.
