DNA-templated transcription initiation
Term Information
Accession
GO:0006352
Name
DNA-templated transcription initiation
Ontology
biological_process
Synonyms
DNA-dependent RNA polymerase complex assembly at promoter, DNA-dependent transcription, initiation, DNA-templated transcription, initiation, initiation of DNA-dependent transcription, initiation of transcription, DNA-dependent, transcription initiation factor activity, transcription initiation, DNA-dependent, transcription initiation from bacterial-type RNA polymerase promoter
Alternate IDs
GO:0001123
Definition
The initial step of transcription, consisting of the assembly of the RNA polymerase preinitiation complex (PIC) at a gene promoter, as well as the formation of the first few bonds of the RNA transcript. Transcription initiation includes abortive initiation events, which occur when the first few nucleotides are repeatedly synthesized and then released, and ends when promoter clearance takes place.

Comment
Note that promoter clearance is represented as a separate step, not part_of either initiation or elongation.
