BIOL 271 Module 6 (Latest Update 2026 /
2027) Microbiology Questions & Answers
{Grade A} 100% Correct - Portage Learning
True of false: Because the genome is contained within an enclosed space (much like
the nucleus of a cell), viruses are classified as eukaryotic. - Correct answer False
Describe the two basic components of a virus. - Correct answer 1) Genomic material
made up of DNA or RNA
2) Capsid, which is a membrane like protective structure that contains genetic
material.
The _____ surrounds the capsid of some viruses. - Correct answer envelope
True of false: You would expect to see a viral envelope on a virus infecting a plant cell.
- Correct answer False
Rank the following viruses based on their size from largest to smallest: - Correct
answer Variolavirus; orthomyxovirus; poliovirus
, True or false: Viral replication occurs after it attaches and enters the host cell. -
Correct answer True
Place the following viral life cycle in order beginning with viral attachment and provide
a description of each step. - Correct answer 1. Attachment: viral receptors bind to host
proteins on the surface of the cells
2. Entry: virus fuses w/host cell membrane and enters the cell
3. Uncoating: viral capsid disassembles
4. Replication: viral genome is the blueprint to make copies of itself
5. Release: new virus are produced and leave the cell
6. New infection: newly produced viruses that left the host cell now go on to infect new
cells.
A virus that infects bacteria is called a [answer 1] and contains a [answer2] sided
polygon capsid. - Correct answer Bacteriophage; 20
