Multiple Choice
Why did early scientists believe that protein, rather than DNA, was the cell's hereditary material?
Because proteins are made of 20 different amino acids and are more complex than DNA
Because proteins are easier to isolate than DNA
Because DNA was thought to be unstable
Because proteins are found in all cell types
