1. Unique triplets promoted the binding of specific tRNAs to the ribosome. 2. Certain organisms can have one or more aminoacyl tRNA synthetases missing. 3. They have separately evolved in both bacteria and eukaryotes from tRNAs . 4. This enzyme participates in cysteine metabolism and aminoacyl-trna biosynthesis. 5. This enzyme participates in glutamate metabolism and aminoacyl-trna biosynthesis. 6. This enzyme participates in tryptophan metabolism and aminoacyl-trna biosynthesis. 7. The synthetase is also modified to recognize only the orthogonal tRNA . 8. Eukaryotic genes containing consistent Met-tRNA with the mismatch codon. 9. Within the genome are 64 tRNA , and three rRNA genes. 10. There are 41 microRNA, 348 tRNA and 2017 rRNA genes.
