Virus

Which part of the phage is the DNA?

• A

• B

• C

• D

Which part of a virus is the protein capsule that houses the genetic material (DNA/RNA)?

• tail

• nucleus

• capsid

• glycoprotein

What do viruses need to reproduce?

• They need genetic material

• They need a host cell

• They need bacteria

• They need insulin

Viruses are...

• prokaryotes

• eukaryotes

• non-living

• endospores

Reasons why viruses are considered non-living is because

• They are not cellular

• They cannot reproduce by themselves

• They cannot produce proteins

• all of the above

What do viruses have in common with living cells? Both...

• store genetic information

• have chloroplasts

• use glucose for cellular respiration

• have endoplasmic reticulum

Which viral life cycle causes the host cell to burst?

• lytic

• lysogenic

What happens in the lysogenic cycle? 

• The virus enters and exits the host cell

• The virus quickly kills the host cell

• The virus injects nucleic acid into the host cell, and the nucleic acid integrates into the host cell's DNA, remaining inactive for a long time

• The bacteria injects DNA into a host cell

A _____ is a virus that enters a bacterial cell.

• endospore

• decomposer

• plasmid

• bacteriophage

What happens in the lytic cycle?

• The virus enters and exits the host cell

• The virus quickly kills the host cell

• The virus sleeps inside the host cell

• The virus remains inactive for a long time
