RNA contains four different nitrogenous bases EXCEPT.
Correct answer: C. Thymine
- A. Adenine
- B. Guanine
- C. Thymine
- D. Cytosine
Explanation
DNA and RNA differ in three ways. 1. The sugar in RNA is ribose while the sugar in DNA is 2-deoxyribose. 2. Four different bases are found in DNA cytosine (C), thymine (T), adenine (A) and guanine (G). In RNA, .thymine does not occur and its place is taken by uracil (U). 3. DNA is nearly always double stranded, while RNA is usually single stranded.

About Ribonucleic Acid (RNA)
Ribonucleic acid is generally a single-stranded nucleic acid containing ribose and uracil instead of thymine. Coverage includes mRNA, tRNA and rRNA, complementary base pairing, transcription and translation, and the differences between RNA and DNA in structure, location and biological function.
