What part of the attached bacteriophage enters through the host cell wall? A. The entire virus B. Only the enzymes necessary for replication C. The nucleic acid D. The nucleic acid and capsid E. The capsid only

Bacteriophages use different mechanisms for host cell infection and viral replication. During the lytic replication pathway, bacteriophages infect the host bacterial cells and immediately build new virions. During which of the key steps is the genome packed into the capsid and phage structures put together?ANSWERReleaseReplicationPenetrationAssembly

Which component belongs to viruses, not cells?A. cytoplasmB. capsidC. ribosomeD. genetic materialE. nucleus

Select the two essential components that all viruses have.Multiple select question.Nuclear membraneEnvelopeInner core with nucleic acidOuter capsidCell wall

Host cells of viruses include A. human and other animals. B. plants and fungi. C. bacteria. D. protozoa and algae. E. All of the choices are correct.

When a virus encounters a host cell, there are several stages that result in the virus reproducing. What is the first stage of a viral infection? Select one:a.The virus injects its nucleic acid into the host cell.b.The virus releases its nucleic acid before making contact with the host cell.c.The virus immediately begins replication of the viral nucleic acid.d.The virus attaches to a host cell receptor site using a protein.
