Gill Sans BoldExercise 4.5: The discovery of mutagensYou have identified historical evidence that radiation can be mutagenic.Illustrate this mounting evidence by drawing a timeline for theidentification and study of mutagens. Use information from this part inyour timeline.Part 4: How genes operate 47
Exercise 4.6: Sickle cell anaemiaSickle cell anaemia is caused by the substitution of one incorrect aminoacid in a protein. Use a simple model (such as diagrams or letters) toexplain how a change to DNA produces this new shape of red bloodcells._____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Exercise 4.7: Antibiotic resistanceAntibiotic resistance is a modern example of ‘natural’ selection.a) What feature of bacteria determines whether bacteria are ‘the fittest’in this example?__________________________________________________________________________________________________________________________________________________________________b) What is the source of this variation in bacteria?____________________________________________________________________________________________________________48 Blueprint of life
