Sample Question
For a couple of decades, biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins, and not DNA. The reason for this belief was that proteins are more complex than DNA. What was the basis of this thinking?

A) Proteins have a greater variety of three-dimensional forms than does DNA

C) Proteins are made of 40 amino acids and DNA is made of four nucleotides

D) Some viruses only transmit proteins

B) Proteins have two different levels of structural organization; DNA has four
