Which type of RNA is primarily involved in transporting amino acids to the ribosome?

tRNA, or transfer RNA, is the type of RNA primarily responsible for transporting amino acids to the ribosome during protein synthesis. Each tRNA molecule is specific to one amino acid and contains an anticodon that pairs with the corresponding codon on the mRNA strand. This interaction ensures that the amino acids are added in the correct sequence to form a functional protein.

In the ribosome, tRNA molecules sequentially deliver the appropriate amino acids, facilitating the assembly of a polypeptide chain. This process is essential for translating the genetic code carried by mRNA into a specific sequence of amino acids, ultimately leading to the formation of proteins that perform various functions within the organism.

While mRNA serves as the template for encoding the amino acid sequence and rRNA is a structural component of the ribosome, tRNA plays the crucial role of bringing the building blocks—amino acids—into the ribosome for protein synthesis. SnRNA, on the other hand, is involved in the splicing of pre-mRNA, which is unrelated to the transport of amino acids.
