RNA plays multiple roles in the cell: a review<br />
Type <strong>of</strong> RNA<br />
Messenger RNA<br />
(mRNA)<br />
Transfer RNA<br />
(tRNA)<br />
Ribosomal RNA<br />
(rRNA)<br />
Functions<br />
Carries information specifying amino<br />
acid sequences <strong>of</strong> proteins from DNA<br />
to ribosomes<br />
Serves as adapter molecule in protein<br />
synthesis; translates mRNA codons<br />
into amino acids<br />
Plays catalytic (ribozyme) roles <strong>and</strong><br />
structural roles in ribosomes<br />
Type <strong>of</strong> RNA<br />
Primary<br />
transcript<br />
Small nuclear<br />
RNA (snRNA)<br />
SRP RNA<br />
Functions<br />
Serves as a precursor to mRNA,<br />
rRNA, or tRNA, before being<br />
processed by splicing or<br />
cleavage<br />
Plays structural <strong>and</strong> catalytic<br />
roles in spliceosomes<br />
Is a component <strong>of</strong> the the signalrecognition<br />
particle (SRP)
