How are bacteria able to change their patterns of protein synthesis so quickly in response to environmental changes?

#Unit 3. Fundamental Processes
  1. mRNAs that are produced are short-lived and degraded within a few minutes of being synthesized.

  2. mRNA have long lifespans, allowing the bacteria to use them many times for translation.

  3. mRNA is stored for later use.

  4. Operons are activated in the presence of transcription factors.
