Messenger RNA (mRNA) - ANS ✔✔Convey genetic information from DNA to ribosomes in the
cytoplasm, where they specify the amino acid sequence of the protein - it is synthesized from
DNA template during transcription
Transfer RNA (tRNA) - ANS ✔✔Single RNA strand - carries a specific amino acid sequence on one
end and a specific anticodon on the other end. The anticodon base pairs with a complementary
codon on mRNA. It helps cell translate an mRNA message into protein
Ribosomal RNA (rRNA) - ANS ✔✔Structural and catalytic roles in ribosomes
Telomerase RNA - ANS ✔✔Used as a template by telomerase to extend telomeres
Small nuclear RNA (snRNA) - ANS ✔✔Structural and catalytic roles in spliceosomes
SRP RNA - ANS ✔✔A component of the SPR (signal-recognition protein) - a protein-RNA
complex that recognizes the signal peptide of polypeptides targeted to the ER
