AP Viruses and Bacteria

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 reproducing viruses as soon as the genetic content enters the host then kills its host cell by lysing?

• lytic
• mitosis
• lysogenic
• S phase

What happens in the lytic cyle?

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus sleeps inside of the host cell
• Virus stay dormant for a long time

Which virus reproduction cycle causes the cell to immediately rupture and die?

• Lytic Cycle
• Lysogenic Cycle
• Mitosis
• Meiosis

Which of the following is one important difference between a virus and a bacterial cell?

• a virus is much larger in size than a bacterial cell
• a virus always causes more severe disease than a bacterial cell
• a virus can never reproduce on its own, but a bacterial cell can
• a virus does not contain genetic material, but a bacterial cell does

What do viruses have in common with living cells? They both

• store genetic information
• have chloroplasts
• use glucose for cellular respiration
• have endoplasmic reticula

The genetic material of a virus is in the form of

• RNA
• DNA
• either RNA or DNA

What is the main function of the projections on the surface of a virus?

• They aid in respiration
• They help the virus grow
• They help the virus invade its host by attaching to specific sites on the host
• They help the virus digest food molecules

During an infection, some viruses remain inside cell but do not cause symptoms of disease. The graphic below depicts the...

•  lytic cycle and the host cell is destroyed by rapidly reproducing viral particles
• lytic cycle and the viral nucleic acid inserts into the host cell chromosome
• lysogenic cycle and the viral nucleic acid inserts into the host cell chromosome
• lysogenic cycle and the viral nucleic acid replicates independently of the host cell chromosome
