BIO 1500 EXAM
1. Virus: An infectious particle consisting of genes packaged in a protein coat.
2. Capsid: The protein shell that encloses the viral genome.
aterial of a virus.
3. Capsomere: A subunit of the capsid, an outer covering of protein that protects the genetic m
4. Viral Envelope: (Derived from membranes of host cells) surround the capsids of influenz a viruses and many
other viruses found in animals. Cotain a combination of viral and host cell molecules.
5. Bacteriophage(phage): A type of virus that infects and replicates within bacteria.
6. Virulent phage: A virus that infects a bacterium and replicates through a lytic cycle, ulti mately leading to the
lysis (bursting) and death of the host cell.
7. Temperate phage: A type of bacteriophage (a virus that infects bacteria) that can exist i n two distinct states
within a bacterial host: a lytic cycle where it replicates and kills the host, and a lysogenic cycle wher e it integrates into
the host's DNA and replicates with the host's DNA.
