Of the 64 codons, 61 represent amino acids, and three are stop signals. For example, the codon CAG represents the amino acid glutamine, and TAA is a stop codon.

For example, mammalian genes frequently use the AGG codon for Arginine. This is an extremely rare codon used by E. coli and correlates with low levels of its corresponding tRNA. Hence, the mammalian protein translates inefficiently in E. coli and produces a low protein yield [5].

codon. A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids. Codons provide the key that allows these two languages to be translated into each other.

n. A codon, AUG in eukaryotes and either GUG or UUG in bacteria, that signals the initiation of translation and the first amino acid in a polypeptide chain. Also called chain initiation codon.

1. Introduction Codon optimization is a technique recently used by many scientists to improve the protein expression in living organism by increasing the translational efficiency of gene of interest [1-4, 6-13, 15-18, 20-28].

The normal base composition is made up of guanine, adenine, cytosine, and uracil. When a cell receives a signal saying that a certain protein is needed, the code for producing protein is made. The DNA double helix unwinds and one strand of the helix becomes a template for producing the protein-coding template.

a triplet in a chain of nucleic acids in mRNA that specifies the order in which amino acids are added. The codon triplet pairs with a sequence of three complementary nucleotides, called the anticodon, present in the anticodon arm of tRNA. Called also triplet. See also deoxyribonucleic acid.

A sequence of three adjacent nucleotides constituting the genetic code that specifies the insertion of an amino acid in a specific structural position in a polypeptide chain during the synthesis of proteins.

Each codon corresponds to a single amino acid (or stop signal), and the full set of codons is called the genetic code. The genetic code includes 64 possible permutations, or combinations, of three-letter nucleotide sequences that can be made from the four nucleotides.

define the term codon
The term codon is defined as a sequence of three Deoxyribo Nucleic Acid or Ribo Nucleic Acid nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. The codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.
