id: GO:0001127
name: transcriptional open complex formation at bacterial-type RNA polymerase promoter
namespace: biological_process
type: go
obsolete: False

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