Shine Dalgarno sequence because it is prokaryotic ribosome.
Shine-Dalgarno motif is present in front of prokaryotic start codons, and is complementary to the 3' end of the 16S ribosomal RNA. Hybridization between the Shine-Dalgarno sequence and the anti-Shine-Dalgarno region of the16S rRNA ( CCUCCU ) helps the ribosome to the start AUG of the mRNA for translation.
Shine Dalgarno sequence is a ribosomal binding site usually present in bacterial and archaeal messenger RNA, located around 8 bases upstream of the start codon AUG. The RNA sequence also facilitate ribosome to the messenger RNA to start protein synthesis by providing the ribosome with the start codon.
