Web24 dec. 2024 · The first step in their processing is the digestion of the RNA to release individual pre-tRNAs. In archaea and eukaryotes, each pre-tRNA is transcribed as a separate transcript. The processing to convert the pre-tRNA to a mature tRNA involves five steps. 1. The 5′ end of the pre-tRNA, called the 5′ leader sequence, is cleaved off. WebtRNA brings amino acids to ribosomes during protein synthesis. tRNA, along with ribosomes, reads the mRNA codes and produces a polypeptide chain that eventually is used to form a functional protein.
