Since diabetics are not able to make enough insulin, scientists use gene engineering to make it for them. they insert the gene that codes for the production of insulin in the plasmid (circular DNA of bacteria ) to create recombinent DNA, and the bacteria will asexually reproduce, making more and more of the insulin in a short amount of time! hope this helped it took me a long time to understand the whole process in this unit!

Answer:
The exons may be defined as the coding region of the RNA that codes for the particular amino acid. The introns are the non coding region of RNA and must be removed in the final RNA product.
Exon shuffling result in the formation of new gene. The alteration of the exon and intron structure leads to the new gene function in evolution. The genes that are favored and conserved in the evolution perform new gene function. The genes that are selected against are deleted during the evolution.
