- 1-e, 2-d, 3-b, 4-c, 5-a — Correct Answer
- 1-d, 2-e, 3-b, 4-c, 5-a
- 1-e, 2-d, 3-a, 4-b, 5-c
- 1-a, 2-b, 3-c, 4-d, 5-e
Explanation:
Correct Answer: 1-e, 2-d, 3-b, 4-c, 5-a
The correct matches for DNA Exchanges & Mutations:
| Term | Match | Key Point |
|---|---|---|
| 1) Transition | e) Replacement of one purine by another purine | A↔G or C↔T (same type) |
| 2) Transversion | d) Replacement of a purine by pyrimidine base | Purine ↔ Pyrimidine (opposite type) |
| 3) Transduction | b) Transfer of DNA from one bacterium to another by bacteriophage | Virus-mediated transfer |
| 4) Conjugation | c) Genetic exchange between two living bacteria by direct contact | Direct cell-to-cell contact |
| 5) Transformation | a) Direct uptake & incorporation of exogenous genetic material in bacterial cell | Bacterial DNA uptake |
Bacterial Genetic Transfer Methods
- Transformation: Bacterium picks up free DNA from environment
- Transduction: Bacteriophage carries DNA between bacteria
- Conjugation: Direct contact between bacteria (F-factor / plasmid transfer)
