Eukaryotes MetHtRNA tRNA Met+ Methionine Archaeans - Initiation fMetH tRNA Met Bacteria +CHO All cells tRNAMet+Methionine → MetHtRNA一→ Elongation Two types of methionine trNA (tRNA Met or tRNAMet in bacteria and tRNAMet are found in all cells Both trNas are recognized by the same Met-tRNA Synthetase.Two types of methionine tRNA (tRNAi Met or tRNAfMet in bacteria, and tRNAMet) are found in all cells. Both tRNAs are recognized by the same Met-tRNA synthetase
