A type of RNA, distinguished by its length and abundance, functioning in protein synthesis as a component of ribosomes.
A small RNA molecule, consisting of a strand of nucleotides folded into a clover-leaf shape, that picks up an unattached amino acid within the cell cytoplasm and conveys it to the ribosome for protein synthesis.
