General Information
Term transcription preinitiation complex assembly ID (Ontology) GO:0070897 (Gene Ontology)
Definition The formation of a large multiprotein-DNA complex that self-assembles on gene promoter through the sequential recruitment of the general initiation factors that compose the preinitiation complex (PIC). The PIC engages the RNA polymerase on its DNA template strand and sparks polymerization of the first few RNA nucleotides.
Also Known As"DNA-dependent transcriptional preinitiation complex assembly" ; "DNA-templated transcriptional preinitiation complex assembly"
