Question

Which statement about RNA is FALSE?

A. RNA is double stranded RNA contains the sugar ribose
B. RNA contains a nitrogen base called uracil
C. RNA contains a nitrogen base called adenine
D. RNA is composed of building blocks called nucleotides

Answer 1

The false statement about RNA is that it is double-stranded, which is incorrect as RNA is typically single-stranded. RNA does contain ribose and the base uracil, and is composed of nucleotides including adenine.

Step-by-step explanation:

Incorrect Statement about RNA

The statement about RNA that is FALSE is: A. RNA is double stranded RNA contains the sugar ribose. This statement is incorrect because RNA is usually single-stranded, not double-stranded like DNA. RNA does contain the sugar ribose, which differentiates it from DNA's sugar, deoxyribose. In RNA, the nitrogenous base uracil replaces thymine found in DNA, and RNA is indeed composed of building blocks called nucleotides that include the nitrogenous base adenine, among others.

Answer 2

The false statement is A. RNA is double stranded.

Step-by-step explanation:

RNA isn't double-stranded, it only has one strand. RNA is a genetic molecule that is formed through the transcription process. There are many kinds of RNA, the most important ones are mRNA (messenger) and tRNA (transfer) that are involved in transcription in order to synthesize proteins.
