Question:
Richard Ebright was a successful scientist who gave a new theory of cells to thie scientific world. Elucidate.
Answer:
Richard Ebright conducted an experiment on a flock of butterflies and raised the eggs of female monarchs. In addition to this, he also studied the cause of a viral disease that killed all Monarch caterpillars. He also tried to find out similarities between viceroy butterflies and monarch. The study of insect hormones helped him in giving a new theory on the life of cells. Eventually, he was able to find the hormone behind the full development of a butterfly wings. All these experiments led him to conclude that cells grew from a monarchs wings. He found that cells would divide and grow into a normal butterfly if they were fed a hormone that was found in the gold spots of the monarch. Hence, he proved a new theory which formed the blue print of DNA. The experiments conducted by Ebright amply show him to be a successful scientist.
Answer:
Richard Ebright conducted an experiment on a flock of butterflies and raised the eggs of female monarch butterflies. He tried to answer a simple question “what is the purpose of the twelve tiny golden spots on a monarch pupa ? ” To find the answer, Richard first had to build a device that showed the spots producing a hormone. In his senior, he grew cells from a monarch’s in a culture and showed that the cells would divide only if they received the hormone from the spots. In his freshman year at Harvard using the sophisticated equipment, he was able to identify the hormone’s chemical structure. Using this information, he was able to device a new theory. One that showed how the cell could read the DNA.
