Answer:
Explanation:
Ebright discovered a hormone that was necessary for the growth of a butterfly. His other important contribution proved to be his study of how cells read their DNA.
He grew cells from a Monarch's wing in a culture and showed that the cells would divide and develop into normal butterfly wing scales only if they were fed the hormone from the gold spots
All these experiments led him to conclude that cells grew from a monarch's 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.
Ebright's mother Jacqueline Katherine Ebright was the most important person in EBright's life. He had lost his father early and his mother took great pains to bring him up. She bought him a lot of books, microscopes, telescopes, and cameras to kindle his interest.
Ebright used to tag butterflies wings and let them go. In fact, the basement of his house was home to thousands of monarch butterflies. He started losing interest in it because it was a tedious job and there wasnt much feedback.
