Question

Which two statements describe the features of DNA that were revealed by the

combined experiments of Franklin, Watson, and Crick?
A. The amount of adenine equals the amount of cytosine.
B. The nitrogenous bases form specific pairs on the inside of the
molecule.
C. The molecule is wrapped around proteins called histones.
D. The shape of DNA is a double helix.

Answer 1

The features of DNA revealed by the experiments of Franklin, Watson, and Crick are specific base pairing and the double helix structure.

Step-by-step explanation:

The two statements that describe the features of DNA revealed by the combined experiments of Franklin, Watson, and Crick are:

1. The nitrogenous bases form specific pairs on the inside of the molecule. This refers to the complementary base pairing of adenine with thymine and cytosine with guanine.
2. The shape of DNA is a double helix. This refers to the twisted ladder-like structure formed by two strands of nucleotides held together by hydrogen bonds between the base pairs.

The other two options, A. The amount of adenine equals the amount of cytosine, and C. The molecule is wrapped around proteins called histones, are not features directly revealed by the experiments of Franklin, Watson, and Crick.
