PRESCOTTS MICROBIOLOGYCHAPTER 7 QUESTIONS AND ANSWERS
WITH SOLUTIONS 2024
The reproductive strategies of a Eukaryotic Microbe? - 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? - ANSWER - Haploid Only
- Asexual-
- All must replicate and segregate their genome prior to cell division
Asexual in Bacteria and Archaea - ANSWER binary fission, budding, filamentous
Sequence of events from formation of new cell through the next cell division. Associated with binary
fission. - ANSWER Bacterial Cell Cycle
What two pathways function during the Bacterial Cell Cycle? - ANSWER - DNA replication and partition
- Cytokinesis
Site at which replication begins - ANSWER Single origin of replication
Site at which replication is terminated, located opposite of the origin - ANSWER Terminus
Group of proteins needed for DNA synthesis - ANSWER Replisome
Most bacterial chromosomes are: - ANSWER circular
DNA replication process in what direction from the orgin which move to opposite ends of the cell? -
ANSWER Both directions
, Formation of cross walls between daughter cells - ANSWER Septation
In septation, which step occurs first? - ANSWER Selection of site for septum formation
In septation, what is the second step that occurs? - ANSWER Assembly of Z ring
The Z ring is composed of? - ANSWER protein FtsZ
In septation, the third step that occurs is? - ANSWER Assembly of cell wall synthesizing machinery
In septation, what is the last step that occurs? - ANSWER Constriction of cell and septum formation
Tubulin homologue, found in most bacteria and archaea. Polymerization forms Z ring, filaments of
meshwork. - 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. - ANSWER MinCDE, limits Z ring to cell center
Anchoring proteins link Z ring to the plasma membrane - ANSWER Divisome Forms
Cell wall- synthesizing machinery assembled - ANSWER Divisome Forms
The Z ring constricts, the plasma membrane invaginates, and septal wall synthesis/ division is completed
- ANSWER Divisome Forms
Sensitive to osmostic concentration of the environment - ANSWER Plasma Membranes
Water moves into a cell and can cause lysis - ANSWER Hypotonic Conditions
