Many times a change in the base sequence during DNA replication will cause a mutation but if it is the 3rd base often there will be no mutation . It will often give the same protein. The term is genetic "wobble" and is seen when mRNA and tRNA match do not match at the third base.

Mutation
Many things can cause mutations like Radiation,Changing habitat[eg.The Peppered moth],and of course by constant change from generation to generation.
The pairing of bases during replication is very much essential for transmission of inherited traits from parent to offspring because if we did not have these we wouldn't be any different than anyone else in the world. Our genetics make us who we are today.

DNA replication is a semi-conservative process. The DNA is split into two strands. Nucleotides are then attached to each strand by complementary base pairing, where A attaches to T and G attaches to C. The newly formed strand is hence identical to the old strand and the base sequence of DNA can hence be conserved during replication.
A cell's DNA is copied during replication.
This is a frameshift mutation and will render the rest of the DNA sequence useless.
