@XxlightxX Transfer ribonucleic acid (tRNA) is primarily synthesized from tRNA gene through transcription by RNA polymerase and becomes the mature form via several steps: processing, splicing, CCA addition and posttranscriptional modification (onlinelibrary.wiley.com/doi/abs/10.1002/9780470015902.a0000529.pub2#:~:text=Transfer%20ribonucleic%20acid%20(tRNA)%20is,CCA%20addition%20and%20posttranscriptional%20modification.) The synthesis of tRNA is just like the same with the synthesis of other proteins, it is encoded in the gene and then transcribed by RNA polymerase and translated into amino acids
