Which viruses can convert normal cells into cancer cells?
Correct answer: A. Retrovirus
- A. Retrovirus
- B. Adenovirus
- C. Poliovirus
- D. All of the above
Explanation
Retroviruses are a type of virus that can potentially convert normal cells into cancer cells. Retroviruses, like the human immunodeficiency virus (HIV), have an RNA genome that is reverse transcribed into DNA and integrated into the host cell's genome. This integration process can disrupt normal cellular genes or regulatory elements, leading to uncontrolled cell growth and potentially causing cancer.

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.
