22.1: Gene regulation: Introduction - Biology LibreTexts
CAUTION: Depending on your instructor, you may cover a few real biological examples of positive and negative regulatory mechanisms. These specific examples will use the common names of the transcription factors - since the the examples will typically be drawn from the bacterial literature, the names of the transcription factors may include the terms "repressor" or "activator".

Chapter 17. Regulation of Gene Expression – Introduction to Molecular ...
The final level of control of gene expression in eukaryotes is post-translational regulation. This type of control involves modifying the protein after it is made, in such as way as to affect its activity. One example of post-translational regulation is enzyme inhibition.

Cell Cycle - Definition, Phases, Examples, Regulation - Biology Dictionary
Cell Cycle Regulation It’s very important for the survival of cells and organisms that the cell cycle be regulated. Organisms need to be able to stop cell division when the cell in question is damaged, or when there isn’t enough food to support new growth; they must also be able to start up cell division when growth or wound healing are needed.
