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. transcription initiation, DNA-dependent Note that promoter clearance is represented as a separate step, not part_of either initiation or elongation. biological_process DNA-templated transcription, initiation GO:0006352 RNA biosynthetic process
