Two additional categories of RNA play a critical role in the translation process: tRNA and rRNA. Ribosomal RNA (rRNA) molecules were initially characterized by how rapidly they would "sink" in a ...

The tRNA binds to its corresponding amino acid and transports it to the ribosome, where it is incorporated into the growing polypeptide chain. Ribosomal RNA (rRNA) is a component of the ribosomes, the ...

Transfer RNA (tRNA) and ribosomal RNA (rRNA) are involved in the translation of mRNA into proteins. Various non-coding RNAs also play important roles in regulating gene expression and cellular ...

Within the ribosome, the mRNA and aminoacyl-tRNA complexes are held together closely, which facilitates base-pairing. The rRNA catalyzes the attachment of each new amino acid to the growing chain.
