Gene Regulation 1. transcriptional control- affects the selection of genes to be transcribed and the rate of transcription a. most common means of gene regulation b. regulatory proteins bind to a DNA sequence which inhibits or facilitates the binding of RNA polymerase c. 2. posttranscriptional control- affects the processing of mRNA 3. mRNA transport affects the rate at which mRNA leaves the nucleus 4. mRNA degradation occurs because some mRNA transcripts contain sequences
