Wobble pairing lets the same tRNA recognize multiple codons for the amino acid it carries. For example, the tRNA for phenylalanine has an anticodon of 3′-AAG-5′. It can pair with an mRNA codon of either 5′-UUC-3′ or 5′-UUU-3′ (both of which are codons that specify phenylalanine).

The genetic code (article) | Khan Academy
As we saw above, the genetic code is based on triplets of nucleotides called codons, which specify individual amino acids in a polypeptide (or stop signals at its end). The codons of an mRNA are read one by one inside protein-and-RNA structures called ribosomes, starting at the 5′ end of the gene and moving towards the 3′ end. Let’s …

2.3: Genetic Code and Translation – Biology LibreTexts
Sets of three nucleotides that code for a specific amino acid are known as codons. These codons are recognized by, and base pair with, the tRNA molecule with the complementary sequence called anticodon. tRNA molecules act as translators because they are able to read the nucleic acid words (as ) and deliver the corresponding words (as …

Codon optimality, bias and usage in translation and mRNA decay
The use of 3-letter codons in mRNA means that 64 possible codons encode a pool of 20 amino acids and translation stop signals. This has led to degeneracy in the genetic code, where multiple codons …

tRNA Molecules Match Amino Acids to Codons in mRNA. The codons in an mRNA molecule do not directly recognize the amino acids they specify: the group of three nucleotides does not, for example, bind directly to the amino acid. Rather, the translation of mRNA into protein depends on adaptor molecules that can recognize and bind both to the and

Each tRNA anticodon can base pair with one of the mRNA codons and add an amino acid or terminate translation, according to the genetic code. For instance, if the sequence CUA occurred on an mRNA template in the proper reading frame, it would bind a tRNA expressing the complementary sequence, GAU, which would be linked to the amino acid leucine.

Translation of mRNA – The Cell – NCBI Bookshelf
Translation Factors. The first translation step in bacteria is the binding of three initiation factors (IF-1, IF-2, and IF-3) to the 30S ribosomal subunit ( Figure 7.9 ). The mRNA and initiator N -formylmethionyl tRNA then join the complex, with IF-2 (which is bound to GTP) specifically recognizing the initiator .

Hirsh identified a tRNA Trp that inserts tryptophan at UGA stop codons. The tRNA contains a G to A change in the D-arm resulting in U-A rather than U-G base pair, demonstrating that tRNA properties independent of the anticodon can affect decoding. … In a somewhat related process, bacteria use a remarkable dual-purpose -, SsrA, to …
