The RNA responsible for bringing amino acids to the ribosome (the protein synthesis factory) is transfer RNA (tRNA).

Here's why:

* tRNA structure: tRNA molecules have a unique cloverleaf structure. One end of the tRNA molecule has an anticodon, which recognizes a specific codon on the messenger RNA (mRNA). The other end of the tRNA molecule carries the specific amino acid that corresponds to the codon.

* tRNA function: During translation, tRNA molecules bind to the mRNA at the ribosome, bringing the correct amino acid to the growing polypeptide chain. This process ensures that the amino acids are added to the chain in the correct order, according to the genetic code carried by the mRNA.
