After finding a gene that causes a disease, researchers often introduce the defective allele into mice to create an animal model of the disease. Why are these models valuable?a. They allow the testing of potential drug therapies without endangering human patients.b. They allow the sequencing of the mutant allele.c. They allow the production of large quantities of the defective gene product, usually a protein.d. They allow the study of how the gene was transmitted from parents to offspring.
