How Can Regulation be Accomplished? Chemotaxis by Pseudomonas aeruginosa requires regulation of macromolecules in response to signals. Protein regulation is very important and can be grouped into two categories: those that are based on protein activity and those that are based on the amount of protein present ,write the type of regulation described that does not affect the amount of protein present. 1. regulating amount of mRNA made
2. catabolite repression
3. post-translational modification small RNA (sRNA) regulation regulation of transcription
4. attenuation controlling whether mRNA is translated

3. post-translational modification small RNA (sRNA) regulation regulation of transcription

Explanation:

The post-translational modification does not affect the amount of protein present because this type of change is only done to the protein when the translation process has finished, and there is a protein as a result. After the translation, the final product can suffer modifications such as the addition of different components, or enzymatic modifications. In other words, they are chemical changes that the protein experiences that do not affect the amount of protein present.
