Nucleosome Remodeling: DNA wrapped around histones (nucleosomes). SWI/SNF complex remodeling chromatin; HATs adding acetyl groups. Mutation labels: "SWI/SNF loss → condensed chromatin". Pre-Initiation Complex: TATA box with TFIID (TBP), TFIIH, RNAPII, and Mediator complex. Phosphorylation of RNAPII CTD. Aberrancy: "TBP mutation → no promoter binding". Initiation/Unwinding: TFIIH helicase (XPB/XPD) unwinding DNA helix. ATP molecules shown. Mutation: "XPB defect → impaired unwinding".
