Answer
The answer is **c. cell wall**.
Solution
To determine which option is NOT a common feature of viruses, let's analyze each choice:
a. **Envelope**: Many viruses have an envelope, which is a lipid membrane that surrounds the viral capsid. However, not all viruses have an envelope.
b. **Genetic material, which can be double-stranded or single-stranded**: This is a common feature of viruses. They all contain genetic material, which can be either double-stranded or single-stranded.
c. **Cell wall**: Viruses do not have a cell wall. They are not cellular organisms and do not possess structures like cell walls that are found in bacteria and plant cells.
d. **Genetic material, which can be DNA or RNA**: This is also a common feature of viruses. They can have either DNA or RNA as their genetic material.
Based on this analysis, the correct answer is:
**c. cell wall**.

Viruses are fascinating entities that straddle the line between living and non-living. They consist of genetic material encapsulated in a protein coat, and some are covered with an envelope derived from host cell membranes. However, unlike bacteria, viruses lack a cell wall, making option c the odd one out! In the real world, understanding viruses is crucial, especially in medicine. For instance, the COVID-19 pandemic underscored the importance of studying viral structures and genetic material, leading to rapid vaccine development and public health strategies. This ongoing research can help us combat future viral threats and improve global health responses!
