Soru

Zorluk: OrtaViruses: Structure and Characteristics

A mature virus particle (virion) isolated outside a host cell contains functional ribosomes and metabolic enzymes capable of synthesizing proteins independently.

Cevap: Cevap

Cevap

The statement is False because viruses lack ribosomes and metabolic enzymes, making them incapable of independent protein synthesis.
The statement is false because viruses are non-cellular (acellular) biological agents that lack ribosomes, cytoplasm, and ATP-generating enzymes, making independent protein synthesis impossible.

Adım Adım Çözüm

1
Examine the structural components of an extracellular virion.
A virion consists solely of a nucleic acid genome (DNA or RNA) enclosed within a protein coat (capsid), and occasionally a lipid envelope, but completely lacks cytoplasm and cell organelles.
Structural analysis reveals whether protein translation machinery is present.
2
Assess the metabolic capabilities of viruses outside a host cell.
Without ribosomes or ATP-generating metabolic enzymes, a virus cannot synthesize proteins or carry out metabolic reactions independently.
Confirming the inability to perform independent protein synthesis establishes that the statement is false.
