What is the result if transposons are inserted into another region?

• A. Chromosomal Translocation
• B. Mutation
• C. Gene Amplification
• D. No Effect

Answer: (B)

When a transposon moves into a new genomic region, it changes the DNA sequence at that location or alters how that region is regulated. That kind of change is a mutation—the DNA has been altered from its original state. If the insertion lands inside a gene, it can disrupt the coding sequence and disrupt the protein, often causing loss or change of function. If it inserts into a promoter or enhancer, it can change how much or when the gene is expressed. Even if the insertion ends up in a noncoding stretch that doesn’t immediately affect a gene, it still represents a genomic change, i.e., a mutation. Other scenarios like swapping chromosome segments between regions (translocation) or simply increasing gene copy number (amplification) describe different phenomena and are not the direct consequence of a single insertion event. So the result of a transposon inserting into another region is best described as a mutation.
