Questions: 98 | Attempts: 6021 | Last updated: Apr 3, 2025

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. This is because

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

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

Proteins are made of 20 amino acids and DNA is made of four nucleotides.

Only A and C are correct.

A, B, and C are correct.
