- The gene that encodes Factor VIII, a protein that functions in the blood-clotting pathway, contains ___ exons. Mutations in this large gene are responsible for the most prevalent form of the blood disorder hemophilia.
- The research shows that a 40- year-old man passes on an average of _________________ mutations to the child,
- Normally, if a healthy cell acquires too many mutations to develop properly, the p53 gene will initiate cellular suicide. If this gene stops working, however, the cell keeps growing and can become malignant .
- Mutations<br/>of many bacteria have relations with nutrients in culture medium and<br/>culture condition.
