Read What Transgenic Organisms Are Used For
Transgenic plants and animals support agriculture, research and the production of useful biological products.
Transgenic Organisms is the central idea in this question pattern. Identify the condition in the stem before applying the method below.
Read the application
Genetically engineered crops can carry traits such as herbicide tolerance. Transgenic animals are used in vaccine-safety tests, biological-product production and trials of treatments. Mice are the most common transgenic animal model.
Keep historical examples straight
Rosie, an early transgenic cow, produced milk enriched with a human protein; check the named organisation against the source rather than confusing it with later commercial developers.
Synchronise a donor cell for cloning
Somatic-cell nuclear transfer works best when the differentiated donor nucleus is pushed out of active division so it can be reprogrammed by the enucleated egg. Nutrient starvation arrests the cultured donor cell in the quiescent G1-like state used in the source question. Choose B.
