Mutations in DNA

What does the ... mean in the following DNA sequence?

...ATC CCG GGG...

• The ... does not mean anything

• The ... means that there is more DNA in front and behind the ...

There is an addition mutation in the Mutated DNA below where A is added between the C and T. Why are the extra letters "AA" added at the end?

DNA: ...CTA TTT CAG...

Mutated DNA: ...CAT ATT TCA GAA..

• There are also an addition mutation

• There are the two letters that would have come after CAG already. They're part of the ...
