What do viruses & bacteria have in common? (Multiple correct answers)

• Contain Genetic Material

• Pathogenic

• Can be treated with antibiotics

• Evolve over time

• Need a host

All viruses contain the following (choose 2)…

• Nucleus

• Flagella

• Genetic Material

• Capsid (Protein coat)

• Ribosomes

What type of viruses ONLY infect bacteria?

Match the following

• Treat with antibiotic

• Infected with bacteria infection

• Vaccines

• Prevent a viral or bacteria infection by prepping immune system

• Treat with antiviral

• Only infects bacteria

• Bacteriophage

• Infected with a specific type of virus

How do viruses replicate? (Correct order)

• Cell bursts and new viruses continue to spread

• Takes over nucleic acid in cell

• Assemble virus parts

• Attach to host cell

• Inject the virus genetic material

Answer explanation

What happens in the lysogenic cycle?

• The virus’ genetic material is integrated with the host cells chromosomes

• The virus takes over the host cell’s genetic material & created new cells till the host cell bursts

• Kills the host cell right away

• Doesn’t affect the host cell
