Which one of the following statements about RNA is incorrect?
a. RNA molecules are capable of evolving their enzymatic activity over time.
b. RNA is usually found in double-stranded form, just like DNA.
c. RNA molecules are typically shorter than DNA molecules.
d. RNA molecules can form base pairs within a single strand.
e. The nucleotide at the 5' end of an RNA molecule is typically a nucleoside triphosphate.

B

Explanation:

Ribosenucleic acid (RNA) and Deoxyribosenucleic acid (DNA) are the two nucleic acids formed from building blocks called nucleotides. Although, they are formed from the same building blocks, but have structural differences.

One of the differences between RNA and DNA is that unlike DNA that is a double-stranded molecule formed by the complementary base pairing of two nitogenous bases (nucleotides), RNA is a single-stranded molecule made up of shorter nucleotides.

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
