TEST BANK PRESCOTT'S MICROBIOLOGY CHAPTER 7-9
QUESTIONS AND ANSWERS
The reproductive strategies of a Eukaryotic Microbe? - CORRECT ANSWER✅✅✅-
Asexual and sexual. Both have a sexual and an asexual part of the cycle.
- Haploid or diploid
The reproductive strategies of Bacteria and Archaea? - CORRECT ANSWER✅✅✅-
Haploid Only
- Asexual-
- All must replicate and segregate their genome prior to cell division
Asexual in Bacteria and Archaea - CORRECT ANSWER✅✅✅binary fission, budding,
filamentous
Sequence of events from formation of new cell through the next cell division. Associated with
binary fission. - CORRECT ANSWER✅✅✅Bacterial Cell Cycle
What two pathways function during the Bacterial Cell Cycle? - CORRECT
ANSWER✅✅✅- DNA replication and partition
- Cytokinesis
Site at which replication begins - CORRECT ANSWER✅✅✅Single origin of replication
Site at which replication is terminated, located opposite of the origin - CORRECT
ANSWER✅✅✅Terminus
Group of proteins needed for DNA synthesis - CORRECT ANSWER✅✅✅Replisome
Most bacterial chromosomes are: - CORRECT ANSWER✅✅✅circular
, DNA replication process in what direction from the orgin which move to opposite ends of the
cell? - CORRECT ANSWER✅✅✅Both directions
Formation of cross walls between daughter cells - CORRECT ANSWER✅✅✅Septation
In septation, which step occurs first? - CORRECT ANSWER✅✅✅Selection of site for
septum formation
In septation, what is the second step that occurs? - CORRECT ANSWER✅✅✅Assembly of
Z ring
The Z ring is composed of? - CORRECT ANSWER✅✅✅protein FtsZ
In septation, the third step that occurs is? - CORRECT ANSWER✅✅✅Assembly of cell
wall synthesizing machinery
In septation, what is the last step that occurs? - CORRECT ANSWER✅✅✅Constriction of
cell and septum formation
Tubulin homologue, found in most bacteria and archaea. Polymerization forms Z ring, filaments
of meshwork. - CORRECT ANSWER✅✅✅Protein FtsZ
Oscillate from one side of cell to the other. High concentration of MinC at poles preventts
formation of Z ring at those locations. - CORRECT ANSWER✅✅✅MinCDE, limits Z ring
to cell center
Anchoring proteins link Z ring to the plasma membrane - CORRECT
ANSWER✅✅✅Divisome Forms
Cell wall- synthesizing machinery assembled - CORRECT ANSWER✅✅✅Divisome Forms
