Answer:
Insertion
Explanation:
Mutation is a phenomenon in which the nucleotide sequence of a gene in DNA is changed into a new sequence due to insertion, deletion or exchange of a gene segment.
Insertion is a type of mutation in which one or more than pne base sequence in added into the DNA of an organism. This insertion may or may not be dangerous depending on the place of insertion and how it is causing adverse effects on the protein product of the gene.
Here is an example of insertion mutation:
Base sequence: AUG GCC TGC
Product: met ala gln
Insertion:
Base sequence: AUG GCC C TG C
Product: met ala Leu
So we can see that the product protein is changed because of insertion.
