Understanding the Shine-Dalgarno Sequence
The Shine-Dalgarno (SD) sequence is a crucial element in the translation of bacterial mRNAs. It enables the proper positioning of the ribosome at the start codon of the mRNA.
Role of the Anti-Shine-Dalgarno Sequence (ASD)
- The ASD is integral for the ribosome's recognition of the SD sequence.
- It is found within the ribosomal RNA and plays a vital role in initiating translation.
Location of ASD
- The correct answer is option 'C': ASD is present in 16S rRNA.
- The 16S rRNA is part of the 30S ribosomal subunit in eubacteria.
Why Option C is Correct
- The 16S rRNA contains a region that is complementary to the Shine-Dalgarno sequence in the mRNA.
- This complementarity allows for base pairing, facilitating the assembly of the ribosome on the mRNA, which is essential for efficient translation.
Why Other Options are Incorrect
- a) ASD is present in 5S rRNA: 5S rRNA does not participate in the recognition of the SD sequence.
- b) ASD is present in 23S rRNA: The 23S rRNA is part of the larger ribosomal subunit and does not directly interact with the SD sequence.
- d) ASD is formed by interaction of 16S rRNA with 23S rRNA: Although both rRNA components are essential in ribosome function, ASD is specifically a feature of the 16S rRNA.
Conclusion
Understanding the role of the 16S rRNA in the interaction with Shine-Dalgarno sequences is key to grasping the mechanics of bacterial translation. This knowledge is fundamental for fields like microbiology and biotechnology.
