1 Chapter 12: Post-transcriptional Gene Control and Nuclear Transport
~ By Ying Ly (Jessica)

2 Sections: 12.1 Processing of Eukaryotic Pre-mRNA
12.2 Regulation of Pre-mRNA Processing 12.3 Macromolecular Transport Across the Nuclear Envelope 12.4 Cytoplasmic Mechanisms of Posttranscriptional Control 12.5 Processing of rRNA and tRNA

3 Overview from DNA to mRNA

4 5’capping 5’Cap is Added to Nascent RNAs Shortly After the initiation by RNA polymerase II Carboxyl Terminal Domain (CTD) Heteronucleur Ribonuclealus protein (hnRNP) RNA-Binding motifs

5 Conserved RNA-Binding Motifs

6 Cleavage and Polyadenylation of Pre-mRNAs Are Tightly Coupled

7 Splicing: Where it Occurs

8 Splicing: Transesterfications

9 Splicing: snRNA

10 Splicing: Spliceosomes

11 Splicing: Summing it Up
