Unit 1 (Chapters 1-6) Openstax Microbiology
Taxonomy - correct answer is the classification, description, identification and naming of living
organisms.
microorganisms or microbes are - correct answer very small organisms
Viruses - correct answer are generally ultramicroscopic, typically from 20 nm to 900 nm in length. Some
large viruses have been found.
Virions - correct answer are acellular and consist of nucleic acid, DNA or RNA, but not both, surrounded
by a protein capsid. There may also be a phospholipid membrane surrounding the capsid.
Viruses are - correct answer obligate intracellular parasites.
Viruses are known - correct answer to infect various types of cells in plants, animals, fungi, protists,
bacteria and archaea.
Host types for viruses - correct answer are typically limited and infect specific cell types.
Cell shapes of viruses may be - correct answer helical, polyhedral or complex.
Classification of viruses is based on - correct answer morphology, type of nucleic acid, host range, cell
specificity and enzymes carried within the virion.
Like other diseases - correct answer viral diseases are classified using ICD codes.
The stages that viruses follow to infect cells are - correct answer attachment, penetration, uncoating,
biosynthesis, maturation and release
Bacteriophages have a - correct answer lytic or lysogenic cycle
What does a bacteriophage inject into its host cell? - correct answer DNA
