Being able to activate expression of a fluorescent protein when a specific gene is expressed has been most useful for fate mapping in which of the following organisms?



A - C. elegans
B - Frogs
C - Chickens
D - Humans
E - Mice


Answer: E - Mice
Scientists use genetically engineered mice that self-label any gene they choose and those cells' progeny. They are then used to create fate maps for mammals that were not possible before.
