Final answer:
RNA contains ribose sugar, not deoxyribose. It is single-stranded, and uracil replaces thymine, pairing with adenine.
Step-by-step explanation:
The statement about RNA that is not true is the claim that 'It contains deoxyribose sugar.' In fact, RNA contains a different kind of sugar known as ribose, which is distinct from the deoxyribose found in DNA.
Additionally, RNA is typically single-stranded and uses the nitrogenous base uracil instead of thymine, which pairs with adenine. The other base pair in RNA, as in DNA, is guanine with cytosine. This structure makes RNA uniquely suitable for its various functions in the cell, including protein synthesis.
RNA is a single-stranded molecule that contains the sugar ribose and the base uracil instead of thymine. It pairs adenine with uracil and guanine with cytosine. The statement that is not true of RNA is d. It does not contain deoxyribose sugar, which is found in DNA.
