Match each characteristic of viruses in Column A with its corresponding biological implication in Column B.
- Absence of metabolic machinery and organellesRequires obligate intracellular parasitism for replication
- Ability to form crystals outside host cellsDemonstrates non-living chemical property when isolated from host
- Presence of nucleic acid (DNA or RNA)Provides genetic instructions for viral protein synthesis
- Specific surface glycoprotein spikesEnables recognition and attachment to host membrane receptors
Answer
Absence of metabolic machinery and organelles matches with Requires obligate intracellular parasitism for replication; Ability to form crystals outside host cells matches with Demonstrates non-living chemical property when isolated from host; Presence of nucleic acid matches with Provides genetic instructions for viral protein synthesis; Specific surface glycoprotein spikes match with Enables recognition and attachment to host membrane receptors.
The correct matches align viral structural characteristics with their exact biological implications: lack of cellular organelles enforces obligate intracellular parasitism, crystallization demonstrates non-living chemical behavior outside a host, nucleic acids provide genetic hereditary information, and glycoprotein spikes facilitate specific binding to host cell surface receptors.
