Term ID

GO:0001112

Synonyms

• DNA-dependent transcriptional open complex formation
• DNA-templated transcriptional open complex formation
• promoter melting
• transcription open complex formation at bacterial-type RNA polymerase promoter
• transcriptional open complex formation at bacterial-type RNA polymerase promoter

Definition

Any process involved in the melting of the DNA hybrid of the core promoter region within the transcriptional closed complex of an RNA polymerase preinitiation complex (PIC) to produce an open complex where the DNA duplex around the transcription initiation site is unwound to form the transcription bubble.
