The genetic code is degenerate i.e. more than one codon can code for a single amino acid. Due to this, of the 64 codons, 61 codons code for the 20 amino acids.

To encode the 20 amino acids used to assemble proteins, cells rely on 64 triplets of DNA bases (G, C, A, or T/U), called codons. Each codon uniquely specifies an amino acid, such as TCA for the ...

The genetic code consists of 64 triplets of nucleotides called codons, with each codon, except 3, encoding one of the 20 amino acids. There is some redundancy in the code as most of the amino ...

To overcome the inherent challenge of translation termination interference caused by stop codon reprogramming in mammalian cells, researchers from Peking University led by Chen Peng from College of ...

Nevertheless, certain organisms use an extra amino acid, selenocysteine, dubbed the 21st amino acid, which lacks its own codon and uses a stop codon after modifying it.

This experiment demonstrated that messenger RNA transcribes genetic information from DNA, regulating the assembly of amino acids into complex proteins. Nirenberg would go on to decipher the code by ...
