A bacterial culture was sampled hourly for 8 hours after inoculation in fresh media. Cell density was plotted on a semi-log scale.
What does the lag phase represent biologically?
- Acheck_circle
Cells are synthesizing enzymes and adjusting to the new medium before rapid division.
- B
DNA replication is inhibited.
- C
The population has reached carrying capacity.
- D
Cells are dying due to nutrient deprivation.
Explanation
During lag, cells acclimate, synthesize ribosomes/enzymes, and prepare to divide. The population doesn't yet grow exponentially.
