Solution & Step-by-step Explanation

Incorrect: Not all viruses have helical symmetry. Viruses exhibit various symmetries, including helical (TMV), polyhedral/icosahedral (Adenovirus), and complex (Bacteriophage). Other statements are correct: viruses are obligate parasites, unaffected by antibiotics, and use host machinery to replicate nucleic acids and proteins.
