A consensus sequence is, in each case a version of the sequence having at each position the nucleotide (or amino acid) most commonly found there in different examples. Thus, the consensus sequence for promoters in E. coli recognized by RNA polymerase containing s70

Two to four monomers of DnaAATP bind at the origin, and after release of DiaA, they recruit two “pre-priming” complexes of the DnaB helicase bound to DnaC-ATP, so that there is one DnaB–DnaC-ATP complex for each of the two (bidirectional) replication forks.
