What are the three main types of RNA?

Explanation:
Protein synthesis hinges on three RNA molecules that work in sequence to turn genetic information into a protein. Messenger RNA carries the genetic recipe from DNA to the ribosome, providing the codon sequence that specifies the order of amino acids. Transfer RNA acts as the adaptor, matching each codon with the correct amino acid and delivering it to the growing polypeptide chain. Ribosomal RNA forms the core of the ribosome itself, creating the catalytic and structural environment where peptide bonds are formed and translation proceeds. Together, these three RNA types—messenger RNA, transfer RNA, and ribosomal RNA—drive the translation of genetic information into protein. Other RNA species exist that regulate gene expression, but they are not the primary players in this translation process.
