A)It functions as a promoter sequence which recognizes and bonds the sigma factor.
B)It is part of the operator sequence used to control translation.
C)It is a nucleotide sequence involved in initiation of translation.
D)It is a nucleotide sequence involved in termination of translation.
E)none of the above

Question

Quizplus · Accepted Answer

The Shine-Dalgarno sequence is a nucleotide sequence that is involved in the initiation of translation in prokaryotes. It binds to the 16S rRNA of the small ribosomal subunit and helps to position the ribosome at the start codon of the mRNA. It is not a promoter sequence or part of the operator sequence used to control translation, and it is not involved in the termination of translation.
