Vedclass · Answer

(B) Viruses are obligate parasites that require a host cell to replicate. They exhibit various forms of symmetry,including icosahedral and helical,not just helical symmetry. While they use the host's machinery to synthesize their nucleic acids and proteins,they do not possess their own independent metabolic machinery for these processes. Antibiotics target bacterial cell walls or metabolic pathways,which are absent in viruses,making them ineffective against viral infections. Therefore,the statement that 'All of them have helical symmetry' is incorrect.
