UTA Microbiology Exam 3 comprehensive questions fully solved & updated
(Latest Update 2026) UPDATE!!
Binary Fission - (answer)Most common form of bacterial reproduction
4 Basic Steps - (answer)1. Growth of cell size
2. Replication of DNA
3. Division of cytoplasm
4. Septum formation & cell division
Cytokinesis - (answer)Division of cytoplasm
Z Ring Assembly - (answer)FtsZ assembles Z ring to form divisome
Divisome - (answer)Cell division apparatus
Generation Time - (answer)(Doubling Time)-time it takes to double the population
Lag Phase - (answer)Cells adjust to culture medium; no change in population
Log Phase - (answer)Binary fission occurs; cell replication > cell death
Stationary Phase - (answer)Resources become depleted; cell respiration=cell death
Death Phase - (answer)Endospores can form; cell replication < cell death
Close System Cultures - (answer)Have finite resources
