Messanger RNA
mRNA. Single-stranded ribonucleotide product of gene transcription; encodes protein-building instructions.
Ribosomal RNA
rRNA. Structural and functional RNA component of ribosomes.
Transfer RNA
tRNA. A class of small RNA molecules that deliver amino acids to a ribosome; each pairs with an mRNA codon during translation.
Codon
Sequence of three bases in an mRNA strand that codes for an amino acid, or acts as a start or stop signal for translation.
Anticodon
Series of three nucleotide bases in tRNA; can base-pair with an mRNA codon.
Transcription
First stage of protein synthesis, in which a strand of RNA is assembled on a DNA template (gene).
Translation
Second stage of protein synthesis. Information encoded in an mRNA transcript guides the synthesis of a new polypeptide chain from amino acids; occurs at ribosomes.
