A cultured skin fibroblast cell of a goat 'P' was fused with an enucleated ovum of
a goat 'Q'. The resultant activated early embryo was then transplanted into a
pseudopregnant (surrogate) female goat 'R' of the same strain as 'Q'. On
completion of gestation, a female goat 'S' was born. With the exception of
mitochondrial DNA, 'S' is a clone of ________.
Options:
(A) Only P
(B) Only Q
(C) Only R
(D) Both P and R
Official Answer Key:
C
Step-by-Step Solution & Explanation
### **Official Solution & Step-by-Step Derivation (GATE BT 2024 Q.20)**
**1. Governing Concept & Domain**:
This question evaluates **Recombinant DNA Technology** under *Section 3: Recombinant DNA Technology & Genomics* (1 Mark, MCQ).
**2. Molecular / Bioprocess Mathematical Derivation**:
- Formulating the biological principles and kinetic expressions for Recombinant DNA Technology.
- 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)**.
