Which of the following statements does not characterise viruses?
-
The morphology of a virus is determined by the number of the protomeres.
-
Viral nucleic acid is enclosed in a capsid made up of protein subunits called protomeres.
-
All viruses undergo a replication cycle in their human host cell.
-
During the viral replication cycle, an accumulation of mature viruses, incomplete viruses and viral parts occurs within the cell.
-
A virally-infected cell generally presents three signals that it is infected.
The morphology of a virus is determined by the arrangement of the protomeres. When protomeres aggregate into units of five or six (capsomeres) and then condense to form a geometric figure having 20 equal triangular faces and 12 apices, the virus is said to have icosahedral (cubic) morphology. When protomeres aggregate to form a capped tube, they are said to have helical morphology. Any other arrangement of the protomeres results in a complex morphology.
