  • Viruses are not considered living because they

  • What needs a host to survive?

  • What is the structural difference between a viroid and a virus?
    A viroid consists of a single short strand of circular RNA, while a virus contains either DNA or RNA enclosed in a protein coat and sometimes a lipid envelope.
  • How do prions cause disease in the host organism?
    Prions cause disease by inducing normal proteins to misfold, resulting in loss of protein function and leading to slow degenerative diseases.
