transcription initiation from RNA polymerase I promoter for nuclear large rRNA transcript

id: GO:0001180
name: transcription initiation from RNA polymerase I promoter for nuclear large rRNA transcript
namespace: biological_process
type: go
obsolete: False

Description: Any process involved in the assembly of the RNA polymerase I preinitiation complex (PIC) at an polymerase I promoter for the nuclear large ribosomal RNA (rRNA) transcript, resulting in the subsequent synthesis of rRNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. Promoter clearance, or release, is the transition between the initiation and elongation phases of transcription.
