Where do replication, transcription, and translation occur in the cell.
Replication occurs in the nucleus, Transcription occurs in the nucleus (nucleolus), and Translation occurs in the ribosomes on the Rough Endoplasmic Reticulum.
What are the growth phases of exponential growth?
Lag=bacteria synthesizing protein. Log=rapid exponential growth. Stationary= death rate is the same as birth. Death/decline= bacteria population declines exponentially.
What are the byproducts of lactic acid fermentation?
lactic acid.
What happens to pH when CO2 is dissolved?
