Shine-Dalgarno sequence in bacterial mRNA is near:: (A) AUG codon, (B) UAA codon, (C) UAG codon, (D) UGA codon
Answer is A. Ans. A. AUG codon(Ref: Harper 31/e page 395)Shine Dalgarno sequence is the marker sequence. The first AUG codon after Shine Dalgarno sequence is the start codon in bacteria. Similarly in eukaryotes there is Kozak sequence.
