RNA Types

The three principle RNA types are Ribosomal RNA (rRNA): This forms the

“factories” where proteins are made. Transfer RNA (tRNA): This RNA collects

and brings amino acids into the ribosomes for protein synthesis.

Messenger RNA (mRNA): This is the template for which amino acids are placed in the correct order.
