Question

Which of the following statements concerning RNA is false?

a. It contains the base uracil instead of thymine.
b. It is single-stranded.
c. It contains the same sugar as found in DNA.
d. It is able to pass through the nuclear membrane.
e. It is involved in the synthesis of proteins.

Answer 1

The false statement about RNA is that it contains the same sugar as DNA; RNA contains ribose, whereas DNA contains deoxyribose.

Step-by-step explanation:

The statement concerning RNA that is false is: "It contains the same sugar as found in DNA." The sugar in RNA is ribose, which is different from the deoxyribose found in DNA. Here are accurate descriptions of RNA:

• RNA contains the base uracil (U) instead of thymine (T) which is found in DNA.
• RNA is usually single-stranded, unlike the double-stranded structure of DNA.
• RNA can pass through the nuclear membrane via the process of transcription and translation to produce proteins.
• RNA is crucial in the synthesis of proteins, playing roles as messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Therefore, the false statement is that RNA contains the same sugar as DNA.
