Which statement is wrong for viruses?
A
Antibiotics have no effect on them
B
All are parasites
C
All of them have helical symmetry
D
They have ability to synthesize nucleic acids and proteins
Detailed Solution
Viruses are obligate parasites, are not affected by antibiotics, and direct the host machinery to make their nucleic acids and proteins.
Their capsids may be helical (e.g. TMV), polyhedral (e.g. adenovirus) or complex (e.g. bacteriophage).
So the statement that all of them have helical symmetry is wrong.
