Prokaryotes respond quickly to their environments mainly by transcriptional (regulatory proteins bind DNA) control. Translational control also occurs, mediated by stability of the mRNAs. 2. Eukaryotes have more complex means to regulate gene expression, because they have compartments (e.g., nucleus) within cells, and often multicellular structures that require differentiation of cells. 3. Levels at which expression of protein-coding genes is regulated in eukaryotes: a. Transcription. b. mRNA processing and transport. c. Translation. d. Degradation of mRNA. e. Protein processing. f. Protein degradation.application/ppt5002752 bytesapplication/vnd.ms-powerpointzh-TWlearning objecthttp://ntur.lib.ntu.edu.tw/bitstream/246246/2006092815540076/1/ch17.ppt
