WebNTPs, individually or together, had no se-lective effect on n-nB P1 activity (19). Six of the seven E. coli rm P1 promoters begin transcription with ATP, but the rmnD P1 transcript starts with GTP (Fig. 1B). Maximal transcription of rnD P1 in vitro was not selectively affected by varying ATP, UTP, or CTP concentrations, but was Web-transcription, synthesis of RNA identical to one strand/coding strand of DNA; -antisense stand acts as template/is transcribed; -RNA polymerase attaches to sequence of DNA known as promoter (region); -RNA polymerase separates the two strands of DNA; (unwinding) exposes (10-20) DNA bases for pairing with RNA nucleotides;

WebAbortive initiation. Abortive initiation, also known as abortive transcription, is an early process of genetic transcription in which RNA polymerase binds to a DNA promoter and enters into cycles of synthesis of short mRNA transcripts which are released before the transcription complex leaves the promoter.
