Match: Types of Mutations and Their Definitions
Match the column — Mutations and their definitions:
TABLE-I TABLE-II
1. Non-sense mutation a. Any insertion or deletion not evenly divisible by 3
2. Silent mutation b. Any insertion or deletion evenly divisible by 3
3. Mis-sense mutation c. Substitution of one amino acid by another
4. In-frame mutation d. Codes for same amino acid — no visible change
5. Frame shift mutation e. Codes for stop codon and terminates protein synthesis
- 1-e, 2-d, 3-c, 4-b, 5-a — Correct Answer
- 1-e, 2-c, 3-d, 4-b, 5-a
- 1-d, 2-e, 3-c, 4-b, 5-a
- 1-e, 2-d, 3-c, 4-a, 5-b
Correct Answer: 1-e, 2-d, 3-c, 4-b, 5-a
Correct Matching
| Mutation Type | Definition |
|---|---|
| Non-sense mutation | Codes for a stop codon → terminates protein synthesis prematurely |
| Silent mutation | Codes for the same amino acid → no visible change in phenotype |
| Mis-sense mutation | Codes for a different amino acid → substitution of one amino acid by another |
| In-frame mutation | Insertion or deletion evenly divisible by 3 → reading frame maintained |
| Frame shift mutation | Insertion or deletion not evenly divisible by 3 → reading frame shifts |
Types of Gene Mutation by Substitution
- Transition: Purine → Purine OR Pyrimidine → Pyrimidine
- Transversion: Purine → Pyrimidine OR Pyrimidine → Purine
