Which of the following statements about RNA is false?
A
RNA uses the base thymine instead of uracil.
B
RNA can function as a catalyst in biological reactions.
C
RNA contains the sugar ribose.
D
RNA is typically single-stranded.
Verified step by step guidance1
Review the basic structure and components of RNA, noting that RNA contains the sugar ribose and uses uracil as one of its nitrogenous bases instead of thymine.
Understand that RNA is typically single-stranded, which differentiates it from the double-stranded structure of DNA.
Recognize that RNA can have catalytic functions, such as ribozymes, which means RNA can act as a catalyst in biological reactions.
Evaluate each statement given in the problem by comparing it to the known facts about RNA's structure and function.
Identify the false statement by noting that RNA does not use thymine; thymine is found in DNA, while RNA uses uracil instead.
