Which type of RNA carries amino acids to the ribosome?

The type of RNA that carries amino acids to the ribosome is transfer RNA, or tRNA. Each tRNA molecule has a specific anticodon that corresponds to a particular amino acid. This allows tRNA to transport the correct amino acids to the ribosome during protein synthesis. The ribosome reads the sequence of the mRNA, and as it does so, tRNA molecules bring in the appropriate amino acids in the order specified by the mRNA codons, facilitating the formation of a polypeptide chain.

Other types of RNA serve different roles in the cell. Messenger RNA (mRNA) carries the genetic information from DNA to the ribosome for translation but does not interact with amino acids directly. Ribosomal RNA (rRNA) is a structural component of the ribosome itself, playing a critical role in the assembly of proteins but not in transporting amino acids. Small nuclear RNA (snRNA) is involved in the processing of pre-mRNA in eukaryotic cells and does not participate in the translation process. Therefore, tRNA is specifically designed for the essential task of delivering amino acids to the ribosome, making it the correct answer.
