We know that by the process of gradual and continuous change, living organisms have evolved. After a number of experiments, scientists have established that genes are the segments of DNA. These DNA carries genetic information from generation to generation. Richard Ebright worked on his basis. He raised flock of butterflies and raised the eggs of female Monarch. He studied the various stages of female Monarch. He further studied the cause of a viral disease that killed all Monarch caterpillars. Next he tried to find similarities between viceroy butterflies and monarchs. Study of insect’s hormone further give a new theory on the life of cells. They found the hormone behind butterfly’s full development. Thus, all these experiments led him to form a theory that cells grew from a monarch’s wings. The cell would divide and grow in a normal butterfly. If they were fed into a hormone from the gold spots. Thus, he proved a new cell theory which formed the blue print of DNA.
If I am given a chance I would like to work in the sphere of stem cell which has a very wide range and would be a great keep for future.
