Key points: summarized from chapter 14

Key points: summarized from chapter 14. RNA processing. Outline: we will focus on mRNA processing. Overview of the Central Dogma Introns versus exons What is a codon Steps of pre-mRNA processing Eukaryotes versus prokaryotes. 3 steps of mRNA processing occurs in the nucleus of eukaryotes.

Gene Regulation

Gene Regulation. Gene regulation in bacteria and eukaryotes Bacterial cells Grow rapidly and have short life span Transcriptional-level control best Eukaryote cells Long life span Gene regulation complex Transcriptional-level control dominates, but other levels important, also.
