RRNA operon
From GcatWiki
The rRNA operon encodes for the ribosomal RNA, which comprises the ribosomes. Three distinct rRNA sequences exist in the operon, encoding for the two subunits of the ribosome; the 5S and 23S sequences code for the large subunit, while the 16S sequence encodes for the small subunit.
The three sequences are coded in the following order, from 3' to 5': 16S, 23S, 5S.
The 3' end of the 16S RNA, or small subunit, binds to the 5' end of the messenger RNA during transcription, specifically to the Shine-Dalgarno sequence. This aligns the mRNA's start codon for transcription. The 16S rRNA itself contains an anti-Shine-Dalgarno sequence on its 3' end.
