Activity: Ahhh… Relationships!
Page 2 of 4

In the middle of the 20th century, researchers already knew that chromosomes played an important role in heredity, and many suspected that DNA held the precious genetic information from each parent. Perhaps, by viewing a model of DNA, it could be understood how traits from each parent were combined in the offspring.
There was a frenzy of activity from 1940 on. The relationships between the scientists proved to be important to the discovery of DNA in 1953. This activity will reveal more about those relationships. Before you begin, print a worksheet by clicking here to help you keep track of what you learn about the these relationships.

Below this paragraph is an interactive map of these relationships. Compare the images with those in the biographies. Scientists working at the two major labs in the DNA quest are shown, along with the names of the labs. The lines among the scientists and between the labs mark relationships.
