At frighteningly young ages, in their 40s, four of Laura Cuartas's children began forgetting and falling apart, assaulted by what people here have long called La Bobera, the foolishness.
This recitation helps students review and master the concepts of gene expression, as well as modeling a useful study technique. Students work with whiteboards and dry-erase markers while the instructor can walk around to guide/ask probing questions. The activity can be tweaked depending on the instructor's specific expectations for students. Ranking the potential severity of various mutations...
