A scientist is studying a genetic mutation in a particular gene. She observes that there is an insertion of six bases in the gene sequence. Based on this information, what can be inferred about the effect of this mutation?

It will cause a frameshift mutation altering the reading frame of the gene.

It will result in the insertion of two additional amino acids without altering the reading frame from that point onwards.

It will lead to the deletion of two amino acids and change the reading frame.

It will have no effect on the protein synthesized from this gene.
