For their efficient translation, eubacterial mRNAs possess a Shine-Dalgarno sequence for its
recognition by an anti-Shine-Dalgarno sequence (ASD) in the ribosomes. The correct statement is
Options:
(A) ASD is present in 5S rRNA
(B) ASD is present in 23S rRNA
(C) ASD is present in 16S rRNA
(D) ASD is formed by the interaction of the 16S rRNA with the 23S rRNA upon docking of the
50S subunit on the 30S subunit of the ribosomes
Official Answer Key:
C
Step-by-Step Solution & Explanation
### **Official Solution & Step-by-Step Derivation (GATE BT 2014 Q.44)**
**1. Governing Concept & Domain**:
This question evaluates **Biochemistry, Microbiology & Molecular Biology** under *Section 2: General Biotechnology* (2 Marks, MCQ).
**2. Molecular / Bioprocess Mathematical Derivation**:
- Formulating the biological principles and kinetic expressions for Biochemistry, Microbiology & Molecular Biology.
- Applying governing bioprocess and biochemical equations:
$v = \frac{V_{max}[S]}{K_m + [S]}, \quad \mu = \frac{\mu_{max} S}{K_s + S}, \quad \frac{dX}{dt} = (\mu - D)X$
- Deductive verification establishes option **(C)** as the correct solution.
**3. Final Answer**:
Correct Option is **(C)**.
