The main structural components of viruses are
Correct answer
A
Rationale
Step-by-step rationale for choice A:
1. Viruses contain genetic material in the form of nucleic acids (DNA or RNA).
2. Proteins are essential for the structure and function of viral particles.
3. Nucleic acids (genetic material) and proteins are the two main components of viruses.
4. Therefore, choice A (nucleic acid and proteins) is correct.
Summary:
- Choice B (nucleic acids and lipids) is incorrect as lipids are not a main structural component of viruses.
- Choice C (lipids and proteins) is incorrect as nucleic acids are essential components of viruses.
- Choice D (proteins and glycoproteins) is incorrect as glycoproteins are a type of protein and not a separate component in viruses.
