Term Name:	transcription preinitiation complex assembly
Synonyms:	bacterial-type RNA polymerase preinitiation complex assembly, bacterial-type RNA polymerase transcription PIC formation, bacterial-type RNA polymerase transcriptional preinitiation complex formation, DNA-dependent transcriptional preinitiation complex assembly, DNA-templated transcriptional preinitiation complex assembly, transcription PIC biosynthesis, transcription PIC formation, transcriptional preinitiation complex formation
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.
