Transfer RNA (tRNA) is a type of RNA molecule that plays a crucial role in the process of protein synthesis. It acts as a bridge between the genetic code carried by messenger RNA (mRNA) and the amino acids that make up proteins. Each tRNA molecule is specific to one amino acid and has an anticodon that pairs with the corresponding codon on the mRNA strand. During translation, tRNA molecules transport their attached amino acids to the ribosome, where proteins are assembled. The ribosome reads the sequence of codons on the mRNA, and tRNA ensures that the correct amino acids are added in the proper order, ultimately forming a functional protein.
