|
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.
