Answer:
Deletion of two nucleotides.
Explanation:
Every amino acid coded by 3 nucleotides.
12:3=4 (amino acids)
6:3=2 (2 amino acids)
3:3=1 (1 amino acid)
After all of these mutations sequence amino acids change, but after continues stay the same.
Only deletion of 2 nucleotides will completely altered all amino acids encoded without mutation.
