Transcription in Eukaryotes Class II promoters: *Core Promoter TATA box TFIIB Recognition Element (BRE) Initiator (Inr) Downstream Promoter Element (DPE) *Upstream Promoter Element
Transcription Initiation in Eukaryotes General Transcription Factors and the Pre-initiation complex:
Transcription Initiation in Eukaryotes TBP binding:
Elongation of Transcription in Eukaryotes Schematic Model
RNA processing in eukaryotes Addition of poly A tail Addition of 5’cap Splicing Polyadenylation *CstF *CPSF *PAP *PABP
Transcript Processing Formation of the 5’ cap *RNA triphosphatase *guanylyl transferase *methyl transferase
Functions of the Cap and Tail • Protection • Translatability • Transport • Splicing
