These lecture notes cover Topic 12, focusing on RNA-based regulation and its effects on gene expression. The notes provide a comprehensive overview of various RNA regulatory mechanisms in both prokaryotes and eukaryotes, including transcription, translation, and chromatin structure changes. Key topics include mRNA secondary structures, riboswitches, antisense RNA, RNA interference (RNAi), and long non-coding RNAs (lncRNAs). Additionally, the notes explore specific examples and experimental appli...
