Which are paired by a Shine-Dalgarno sequence?
A)the mRNA sequence just upstream from the start codon with the ribosome
B)the first codon of the mRNA with its tRNA
C)a termination codon with a release factor
D)the 30S subunit with the 50S subunit of the ribosome
E)none of the above

Question

Quizplus · Accepted Answer

The Shine-Dalgarno sequence is a region of the mRNA just upstream from the start codon that pairs with a complementary sequence on the 16S rRNA of the 30S ribosome subunit, facilitating the correct positioning of the ribosome on the mRNA.
