Which of the following statements is correct about the molecule shown in Figure 1?
Understand the Problem
The question asks which statement accurately describes the nucleic acid molecule depicted in the figure, with options pertaining to its classification as RNA or DNA based on its characteristics.
Answer
It is DNA because of the hydrogen bonds between guanine and cytosine.
The molecule in Figure 1 is DNA because of the nature of the hydrogen bonds between guanine and cytosine.
Answer for screen readers
The molecule in Figure 1 is DNA because of the nature of the hydrogen bonds between guanine and cytosine.
More Information
DNA is recognized by its characteristic nucleotide pairing: adenine with thymine and guanine with cytosine. The presence of thymine instead of uracil distinguishes DNA from RNA.
Tips
A common mistake is confusing thymine (present in DNA) with uracil (present in RNA).
