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.

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )

The answer is a because - is an direction
