Document Summary

Inducible -> nutrients, stress, hormones: prokaryotic gene organisation: >contains sequences at -10 & -35 bases before transcription start site -> recognised by rna polymerase. Segment of dna -> corresponding -> one polypeptide/protein. (sites -> start/stop of transcription) not = (sites -> start/stop of translation. : eukaryotic class ii (mrna-encoding genes) >complementary sense/coding strand & mrna: transcription bubble: >complementary -> template strand: rna polymerase knows; >>>all info -> found in gene: all genes contain regulatory element. Spacial/temporal/inducibility: prokaryotic genes differ -> organisation & function -> eukaryotic genes. >cistrons vs. introns/exons: transcription initiation -> prokaryotic rna polymerase: > assembly & folding -> required for some genes. Core enzyme (alpha-alpha-beta-beta) -> capable -> elongation: rna polymerases: Pol i - ribosomal rna genes -> rrna. Pol ii - protein coding genes -> mrna. Each type rna polymerase -> distinct set -> accessory/transcription factors: transcription unit: Section of dna -> used -> production -> rna. Nucleotide/protein sequences required for transcription of dna.
