Virus Review

During the lytic infection by a virus, the host cell is-

• destroyed
• copied
• passed on to the lysogenic cycle
• not affected

Which statement regarding viruses is true?

• a virus can only reproduce inside of a living cell
• viruses do not contain DNA
• viruses are unicellular
• viruses are generally larger than cells

What feature do viruses have in common with animal cells?

• ability to form proteins at the ribosomes
• existence of lipids in cell membranes
• presence of genetic code in nucleic acid
• production of energy by a mitochondrion

A(n) _____ is a virus that enters a bacterial cell.

• endospore
• decomposer
• plasmid
• bacteriophage

Which viral life cycle allows viral genetic material to lay dormant while the host cell reproduces?

• lytic
• mitosis
• lysogenic
• S phase

Which viral life cycle kills its host cell by lysing?

• lytic
• mitosis
• lysogenic
• S phase

What do viruses need to reproduce?

• they need genetic material
• They need a host cell
• They need  bacteria
• They need insulin

What happens in the lysogenic cycle? 

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus inject the nucleic acid into the host cell, and the nucleic acid integrates into the host cell DNA, and stay dormant for a long time
• Bacteria injects DNA into a host cell

What process is this?

• phagocytosis
• lytic cycle
• lysogenic cycle
• formation of antibodies

What is shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation
