WebLiving organisms have evolved to have two distinct forms of methionine decoding tRNAs – initiator and elongator. Sequence based analyses of many genomes have indicated that the sequence and copy number of tRNA methionine initiator genes (tRNAi) varies amongst species and strains and tRNAi genes tend to be present in multiple copies. WebEdit: There are some sources that say 48 or 49 aatRNAs, though many tRNA are silent or only expressed at certain times, so there is some debate. I should also add, that those are anticodon families - there are also tRNA isodecoders. Which are tRNAs with the same anticodon but different overall "body" sequence.

The aa-tRNAs typically found in the cell can be divided into three main types (Table 1). The largest group comprises correct pairings of an amino acid and the corresponding tRNA, and they serve as substrates for ribosomal translation.
