Questions & Step-by-Step Solutions

What is the function of a viral envelope?
  • Step 1: Understand that a virus is a tiny infectious agent that needs a host cell to reproduce.
  • Step 2: Know that some viruses have a protective outer layer called an envelope.
  • Step 3: The viral envelope is made of lipids (fats) and proteins.
  • Step 4: The envelope helps the virus attach to the surface of a host cell.
  • Step 5: Once attached, the envelope helps the virus enter the host cell.
  • Step 6: After entering, the virus can use the host cell to make more viruses.
