A sample of RNA is sequenced and found to contain 22% adenine. Which of the following conclusions can also be drawn about the sample?
Correct answer: A. 22% uracil
- A. 22% uracil
- B. 22% thymine
- C. 22% cytosine
- D. 22% guanine
Explanation
In RNA, Adenine forms 2 hydrogen bonds with Uracil and Cytosine bonds with Guanine. But in DNA, Adenine forms 2 hydrogen bonds with Thymine and Cytosine forms 3 hydrogen bonds with Guanine.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
