Question 4
DNA is formed from four nucleobases: Adenine (A), Guanine (G), Cytosine (C), Thymine (T). Mutations create a new sequence.
A species called Vormi has three kinds of mutation:
- Substitution: change one base to another, e.g. AGGTC → AGGTA.
- Deletion: remove one base, e.g. AGGTC → AGTC.
- Duplication: duplicate one base next to itself, e.g. AGGTC → AGGTTC.
Starting from GTATCG, which sequence cannot be produced in three mutations?
