Gene sites sensitive to mutation DNA Components of protein active site Promoter Intron 3' Wild type Exon Exon m1: null m2: null m3: null m4: leaky m5: silent m6: null m2 Active site FIGURE 2-13 Mutations in the parts of a gene encoding enzyme active sites lead to enzymes that do not function (null mutations). Mutations elsewhere in the gene may have no effect on enzyme function (silent mutations). Promoters are sites important in transition initiation. Protein m4 m5 m3 = mutant site
