Final answer:
Messenger RNA is single-stranded and acts as a copy of protein-coding information.
Explanation:
Messenger RNA (mRNA) is indeed single-stranded, serving as a copy of the protein-coding information in DNA. This RNA molecule is complementary to the coding regions of one of the DNA strands of a gene. While RNA is typically single-stranded, it can fold upon itself to form a three-dimensional structure.
