Questions: Which of the following is NOT true about RNA? A. It is single stranded. B. It is a Nucleic Acid. C. It contains Deoxyribose. D. It contains Uracil.

The answer is C: It contains Deoxyribose.

Explanation for each option:

A. It is single stranded.

• This statement is true. RNA is typically single-stranded, unlike DNA, which is double-stranded.

B. It is a Nucleic Acid.

• This statement is true. RNA (Ribonucleic Acid) is indeed a nucleic acid, similar to DNA (Deoxyribonucleic Acid).

C. It contains Deoxyribose.

• This statement is NOT true. RNA contains ribose sugar, not deoxyribose. Deoxyribose is found in DNA.

D. It contains Uracil.

• This statement is true. RNA contains the nitrogenous base uracil, which replaces thymine found in DNA.

In summary, the incorrect statement about RNA is that it contains deoxyribose. RNA contains ribose sugar instead.
