  2. 3. State in which the virus stays hidden and doesn’t cause harm.
  3. 4. The virus quietly integrates itself into the host’s DNA and can stay hidden for long periods of time
  4. 5. Less stable with a high mutation rate which allows for quick adaptation to changing environments and host immune responses.
Down
  1. 1. The virus quickly takes over a host cell and makes many copies of itself.
  2. 2. Tiny particles that contain nucleic acid within a protein membrane.
  3. 3. More stable which makes them less prone to quick breakdown in the environment and directly integrate into the host's genome.
