True or False: DNA differs from RNA because it contains the sugar deoxyribose instead of ribose, it has the base uracil instead of thymine, and it is double stranded rather than single stranded.

This statement is false.

Let’s break it down point by point:

• Sugar: It is correct that DNA contains the sugar deoxyribose while RNA contains ribose. This part of the statement is true.
• Base: The statement claims that RNA has uracil instead of thymine. This is also true because RNA incorporates uracil and DNA uses thymine.
• Strands: Finally, the claim that DNA is double stranded and RNA is single stranded is generally true. While most RNA is single stranded, there are some viral RNAs that can be double stranded.

However, the overall statement fails because it combines both true and false elements, particularly in the context of the phrasing “true or false” regarding direct differences. The confusion lies in the mix of elements that are correct with a misrepresentation. Therefore, while aspects are true, as a whole, the claim misleadingly suggests a single coherent truth regarding the differences.
