During dna replication in a bacterium a g is mistakenly inserted into the newly-synthesized dna strand opposite a t in the template dna strand. if this mistake is not repaired before the next round of dna replication, what mutation will eventually result?

The type of mutation that will eventually occur is A TO G BASE SUBSTITUTION. 
In this type of mutation,  what will happen is that, in all the points where adenine base is suppose to be inserted, it is the guanine base that will be inserted there. This is an example of base substitution error in DNA replication.
