Here's an example of insertion:
A virus inserts it's DNA into a hosts DNA. Using the host, the now viral DNA will create viral parts and assemble more viruses.
To be clearer on what i am asking, for example, 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 ?
