34. The specific sequence on mRNA that guides the prokaryotic ribosome to correctly align with the start codon is the

A. TATA box
B. Shine-Dalgarno sequence
✓
C. Kozak sequence
D. Pribnow box

📝 Explanation

The Shine-Dalgarno sequence is a purine-rich region upstream of the start codon that pairs with the 16S rRNA of the prokaryotic ribosome.
