Abnormalities occur in the chromosomes of living organisms. These chromosomal abnormalities are caused by MUTATION. Mutation is any change in the nucleotide sequence of a gene, which is found on chromosomes.
According to the question, a chromosomal defect that involves the exchange of chromosomal segment between two different chromosomes is called TRANSLOCATION. In Translocation, one part or segment of a chromosome containing genes breaks off and gets reattached to another chromosome in the cell.
If an error occurred when RNA was receiving coding information a protein wouldn't be formed correctly. RNA need's coding information to determine what type of protein it needed to produce. Hope I helped!
