Insertion, deletion, inversion?

[Nec]

i have got a TAT but when it becomes TAC, this is called an insertion, I think its the same as deletion, or inversion, so I am stuck at how to make a difference between them ?
Can you help me ?thanx

You have got a what? I guess that is part of a sequence? You should write down the whole sequence, like TATATATATA, which becomes TATCATATATA with an insertion of a base or TATAATATA with a deletion or ATATATATATAT with an inversion :)
