Final answer:

The correct statement about nucleic acids is that RNA is a long, single-stranded molecule consisting of adenine, uracil, guanine, and cytosine. DNA and RNA are made of nucleotides, with DNA containing deoxyribose and being double-stranded, whereas RNA contains ribose and is typically single-stranded.

Step-by-step explanation:

Select the most correct statement regarding nucleic acids:

c. RNA is a long, single-stranded molecule made up of the bases A, U, G, and C.

Nucleic acids are molecules comprised of nucleotides, which include a pentose sugar, a nitrogen-containing base, and a phosphate group. DNA and RNA are the two primary forms of nucleic acids where DNA contains the sugar deoxyribose and forms a double-helical structure, and RNA contains the sugar ribose and is typically single-stranded.

In RNA, the bases are adenine (A), uracil (U), guanine (G), and cytosine (C), whereas in DNA thymine (T) replaces uracil. RNA is crucial for protein synthesis, serving as a messenger between DNA and the ribosome in this process.
