Question

Scientists bring preconceived ideas to their work. Often these preconceptions make it difficult for them to objectively interpret their data. From the information provided in the Copying the Code module, state one example of a preconceived idea that biased scientific thinking and slowed finding the answer to how DNA is a copying mechanism for hereditary material.

Answer 1

With the limited information you have here (ie: they refer to a module that you didnt post) I'm going to assume they are talking about proteins. Namely early geneticist assumed proteins carried the genetic material because the majority of a cells' mass is in the form of proteins.
