ns; transcribed into a single mRNA. Single mRNA coordinates synthesis of all 3 enzymes. block expression for the Z, Y, A gene. d s to initiate transcription of the lac structural genes protein undergoes allosteric transition (change in shape) altering the DNA-binding site. tched “on” Chapter 10: Regulation of Gene Expression in Prokaryotes I. What affects gene expression? a. Production of RNA – how much RNA is transcribed from the gene. (focus) b. Processing of RNA – RNA splicing (alt. splicing), termination, and export to the nucleus are all subject to regulatory controls effecting the properties/amt of protein product made. c. Stability and Translatability of mRNA – determines how much protein is made from a given amount of RNA. (the more stable the mRNA, the longer it stays, and the more protein it will produce) d. Stability and activity of the protein product – proteins can be inactivated. II.
