Nombra 3 grupos no vivos en el mundo microbiano y describe sus propiedades principales.

Los virus contienen una cubierta de proteína y ADN o ARN. Son parásitos intracelulares obligados de todas las formas de vida.

Los viroides contienen solo una molécula de ARN corta. Causan graves enfermedades de las plantas.

Los priones consisten solo en una proteína que es una versión mal plegada de la proteína celular normal que se encuentra en el cerebro de los animales. Son resistentes a los procedimientos de esterilización usados comúnmente que matan virus y bacterias. Son responsables de enfermedades neurológicas fatales.
