Which of the following ensures proper alignment of the small ribosomal unit on the mRNA during protein synthesis?
A) the anticodon
B) the codon
C) the Shine-Dalgarno sequence
D) the initiation sequence

Question

Quizplus · Accepted Answer

The Shine-Dalgarno sequence is a specific sequence of nucleotides found in the bacterial mRNA that is complementary to a sequence on the 16S rRNA of the small ribosomal subunit. This sequence helps in positioning the small ribosomal unit on the mRNA during translation, ensuring proper alignment for the formation of peptide bonds between the amino acids.
