Match: Types of Mutations
Match the column: Mutations
| TABLE-I | TABLE-II |
|---|---|
| 1) Non-sense mutation | a) Any insertion (or) deletion that is not evenly divisible by 3 |
| 2) Silent mutation | b) Any insertion (or) deletion that is evenly divisible by 3 |
| 3) Mis-sense mutation | c) Which code for different amino acids or Substitution of one amino acid by another |
| 4) In-frame mutation | d) Which code for same amino acid so there is no visible change in phenotype |
| 5) Frame shift mutation | e) Which code for stop codon & terminates Protein synthesis |
- 1-e, 2-d, 3-c, 4-b, 5-a — Correct Answer
- 1-d, 2-e, 3-c, 4-a, 5-b
- 1-e, 2-c, 3-d, 4-b, 5-a
- 1-c, 2-d, 3-e, 4-b, 5-a
Explanation:
Correct Answer: 1-e, 2-d, 3-c, 4-b, 5-a
The correct matches for Mutation types are:
| Term | Match | Key Point |
|---|---|---|
| 1) Non-sense mutation | e) Codes for stop codon & terminates protein synthesis | Premature termination |
| 2) Silent mutation | d) Codes for same amino acid — no visible phenotype change | Synonymous substitution |
| 3) Mis-sense mutation | c) Substitution of one amino acid by another | Wrong amino acid |
| 4) In-frame mutation | b) Insertion/deletion evenly divisible by 3 | Reading frame maintained |
| 5) Frame shift mutation | a) Insertion/deletion NOT evenly divisible by 3 | Alters entire reading frame |
Types of Gene Mutation
| Type | Subtypes |
|---|---|
| Substitution | Transition (purine↔purine or pyrimidine↔pyrimidine) / Transversion (purine↔pyrimidine) |
| Frame shift | Insertion or deletion of nucleotides not divisible by 3 |
