Understanding Viruses

What is the primary reason viruses need to infect a host cell?

• To grow in size

• To perform photosynthesis

• To reproduce and carry out functions

• To generate energy

Which of the following is NOT a characteristic of all viruses?

• Having a membrane called an envelope

• Containing DNA or RNA

• Being able to infect host cells

• Having a protein coat called a capsid

What is the role of the capsid in a virus?

• To provide energy for the virus

• To enclose the virus's genetic material

• To produce viral enzymes

• To help the virus move

How do viruses trick host cells into producing more viruses?

• By changing the host cell's DNA

• By inserting their genetic material and enzymes

• By destroying the host cell's nucleus

• By providing nutrients to the host cell

What happens to a host cell after a virus hijacks it?

• It starts producing viral components

• It becomes immune to further infections

• It becomes a different type of cell

• It dies immediately
