Microbiology 2117 Exam Questions and Answers
100% Correct
What is binary fission?
A method of asexual reproduction where a cell divides into two identical daughter cells.
What happens during the cell growth phase?
Cell mass and size increase, and special enzymes break the wall to allow expansion.
What occurs during the DNA replication phase?
The chromosome is copied in preparation for cell division.
What is generation time in bacterial growth?
The amount of time it takes to complete one cell cycle.
How quickly can E. coli grow under ideal conditions?
E. coli could cover the Earth one foot deep in 36 hours.
What is a lag phase in bacterial growth?
The phase where bacteria adjust to a new environment and replicate DNA before growth begins.
What characterizes the logarithmic (log) phase?
Evident bacterial growth occurs on a logarithmic scale, and bacteria are vulnerable to antibiotics.
What happens during the stationary phase of bacterial growth?
Growth levels off as nutrients become depleted and cells stop dividing.
What is the decline (death) phase in bacterial growth?
