Which nucleic acid is usually single-stranded and uses uracil; functions in protein synthesis and as the genome of some viruses?

Explanation:
RNA is the nucleic acid described here. It is usually single-stranded and contains uracil instead of thymine. In terms of function, RNA plays a central role in protein synthesis: messenger RNA carries genetic instructions from DNA to the ribosome, while transfer RNA brings amino acids and ribosomal RNA helps form the ribosome itself. Some viruses also have RNA as their genome, so this molecule can serve as the genetic material in those viruses. By contrast, DNA is typically double-stranded and uses thymine, and the other terms describe specific nucleotide triplets or a particular type of RNA rather than the molecule as a whole.
