Question: 1 / 400

Which type of RNA carries amino acids to the ribosome?

Messenger RNA (mRNA)

Ribosomal RNA (rRNA)

Transfer RNA (tRNA)

Transfer RNA (tRNA) plays a crucial role in protein synthesis by transporting amino acids from the cytoplasm to the ribosome, where proteins are assembled. Each tRNA molecule is specific to a particular amino acid and has an anticodon region that pairs with the corresponding codon on the messenger RNA (mRNA) strand, ensuring that the correct amino acid is added to the growing polypeptide chain. This process is essential for translating the genetic code found in mRNA into functional proteins.

In contrast, messenger RNA (mRNA) is responsible for carrying the genetic information from DNA to the ribosome, ribosomal RNA (rRNA) constitutes the structural and functional components of the ribosome itself, and signal RNA (sRNA) is typically involved in regulatory roles and is not directly involved in the transport of amino acids.
