There are no widely accepted functions for the resulting truncated RNA transcripts. However, a study in 1981 found evidence that there was a relationship between the number of abortive transcripts produced and the time until long RNA strands are successfully produced. When RNA polymerase undergoes abortive transcription in the presence of ATP, UTP, and GTP, a complex is formed that has a much lower capacity for abortive recycling and a much higher rate of synthesis of the full-length RNA transcript. A study in 2010 found evidence that these truncated transcripts inhibit termination of RNA synthesis by a RNA hairpin-dependent intrinsic terminator.
