Question

Choose the incorrect statement with respect to RNA.

• A. It is single-stranded.
• B. Its bases are adenine, thymine, guanine, and uracil.
• C. It has a sugar-phosphate backbone.
• D. Its sugar is ribose.
• E. It is found in the both nucleus and the cytoplasm of the cell.

Answer 1

Answer: (B)

Its bases are adenine, thymine, guanine, and uracil.

The structure of RNA is very similar to that of DNA, which stands for deoxyribonucleic acid. The main difference is that the ribose sugar backbone in RNA has a hydroxyl group that DNA does not contain. Another difference between the two is that DNA uses the base thymine in place of uracil. DNA and RNA carry genetic information that is transmitted from one generation to the next. The four bases found in RNA are guanine, cytosine, adenine and uracil.
