The Shine-Dalgarno sequence
A) is a purine-rich consensus sequence found in the 5′ UTR of the mRNA.
B) is a pyrimidine-rich consensus sequence found in the 3′ UTR of the mRNA.
C) is a purine-rich consensus sequence found in the 16S rRNA subunit.
D) is a region of the tRNA molecule involved in formation of charged tRNAs.
E) is a consensus sequence involved in the termination of translation.

well the sequence is on the mrna and apart of initiation, which rules out c d e... it's purine rich and begins on the 5' end so it's most likely A.

The Shine-Dalgarno sequence is purine rich.  It forms base pairing with a highly conserved, pyrimidine-rich region of the 16 rRNA which is part of the 30S ribosomal subunit.
