Answer
Substitution: A single base is replaced with another, e.g. ACTTC → AATTC.
Insertion: An extra base is inserted, e.g. ACTTC → ACCTTC.
Deletion: A base is removed, e.g. ACTTC → ATTC.
Chromosomal mutations: Large-scale changes to the structure of chromosomes, e.g. deletion or duplication of a chromosome. (Does not apply here.)
No, none of the sequences from Part 1 above apply to any of the mutation types.
