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.

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

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

D) Some viruses only transmit proteins.

E) A and B are correct.

Answer 1

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

Step-by-step explanation:

Proteins have a more complex nature as compared to DNA. Proteins structural organization is also very different. The three dimensional structure determine the function of protein based on the amino acid sequence. Proteins are the end products of the genetic information which perform the function and have greater variety
