Gurdon experiment
The Gurdon experiment was a landmark 1960s study in developmental biology demonstrating that the nucleus of a differentiated frog cell retains the full genetic information needed to direct the development of an entire organism, thereby proving the principle of nuclear equivalence and cellular reprogramming.

NEDg
Description generation
gpt-5.1
Instruction
Generate a one-sentence description of the target entity. You are given a context triple in the form (subject, predicate, object), where the object is the target entity. # Instructions Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. Avoid repeating the information from the triple, unless really essential. # Response Format Return only the sentence: "Description: [one-sentence description of the target entity]"
