Analyze the statements below, and select those that correctly apply to the unique characteristics of viruses.

To help you analyze the unique characteristics of viruses, I will summarize some of the key features that commonly distinguish viruses from other microorganisms:

1. Intracellular Parasites: Viruses can only replicate inside the living cells of a host organism. They cannot reproduce independently.

2. Lack of Cellular Structure: Viruses are not made up of cells, which is a fundamental characteristic that distinguishes them from bacteria, fungi, and other microorganisms.

3. Genetic Material: Viruses contain either DNA or RNA as their genetic material, but not both. This genetic material is encased in a protein coat called a capsid and sometimes surrounded by a lipid envelope.

4. Host Specificity: Different viruses have specific host ranges, meaning they can infect only certain types of cells or organisms.

5. No Metabolic Activity: Viruses do not carry out metabolic processes on their own. They rely on the host cell's machinery for replication, protein synthesis, and energy production.

6. Size: Viruses are generally much smaller than bacteria and other cellular organisms, often measured in nanometers.

With these characteristics in mind, please provide the specific statements you would like analyzed to determine which correctly apply to the unique characteristics of viruses.
