Pairs with 16s rRNA.
Positions AUG codon correctly.
Pairs with 16s rRNA.
Positions AUG codon correctly.
Updated On: Aug 18, 2026
- To guide initiating AUG codon to its correct position
- Proper alignment of small and large ribosomal subunits
- Initiating the catalytic activity of peptidyl transferase
- Positioning of f-Met-tRNA to P-site of ribosomes
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Shine-Dalgarno sequence is found in prokaryotic mRNA.
It is involved in translation initiation.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand the role of the Shine-Dalgarno sequence.
Step 3: Detailed Explanation:
The Shine-Dalgarno sequence is a ribosomal binding site.
It helps in positioning the initiating AUG codon correctly.
It pairs with the 16s rRNA in the ribosome.
This ensures that the start codon is in the P-site.
Thus, its function is to guide the AUG codon to its correct position.
Step 4: Final Answer:
The Shine-Dalgarno sequence guides the initiating AUG codon to its correct position.
Hence, the correct option is (A).

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Plasmid can replicate independently but not a DNA fragment separated from a eukaryotic chromosome.
Reason (R): Plasmid contain replication origin.
In light of the above statements, choose the correct answer from the options given below. - Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Restriction endonuclease is used to cut DNA molecules for cloning.
Reason (R): Restriction endonuclease enzyme cut DNA molecule of any source into unique short pieces in a sequence specific manner. - If a single strand of DNA contain seven restriction sites for a particular restriction endonuclease and none of the restriction site is present either at 3' or 5' end then this enzyme will form how many DNA fragment reacting on it
