Final answer:
RNA is composed of a single strand of nucleotides with ribose sugar and uracil. Its structure contrasts with DNA, impacting its functions in protein synthesis.
Explanation:
RNA consists of a single strand of nucleotides that contain a sugar molecule, a phosphate group, and a nitrogen base. Unlike DNA, RNA uses ribose sugar and uracil as one of its bases instead of thymine. The single-stranded structure of RNA allows it to play essential roles in protein synthesis by carrying out the instructions encoded in DNA.
