An example of an analogy used in popular science writing:
"A normal gene contains from five to 30 GAA repeats but a mutated gene contains from 70 up to 1,000 repeated GAA motifs. … The big GAA expansion acts as a 'sticky' region, which prevents good copying of the DNA. It's analogous to trying to photocopy a 50-page document, when pages four to twelve have been glued together. They won't feed into the copier, and the process grinds to a halt, for that particular document. In the case of the Freidreich's ataxia gene, no copying means no RNA, which means no protein."
