WebApr 1, 2012 · In prokaryotes, the promoter consists of 2 short sequences at the − 10 and − 35 positions upstream from the transcription start site (1). The length of a RBS varies from 3 to 9 nt, and the distance between the RBS and the initiation codon ranges from 5 to 13 nt (7). Webover, the efficiency of ribosome binding to the RBS depends on mRNA structure. Typically, a linker DNA sequence between the end of one gene and the RBS for the next one needs to be introduced.
