codon Definition

co·don (dän′)

noun

a small group of chemical units, consisting of a sequence of three nucleotides, that codes the incorporation of a specific small group of amino acids into a protein molecule during the synthesis of the protein; codons are present in DNA and RNA

Etymology: cod(e) + -on, as in proton

codon Usage Examples

Converse of object

  • stop: By default, only the start and stop codons at the beginnings and ends of open reading frames are shown in the frame display.
  • introduce: The second mutation introduces a premature stop codon in the mature protein 34.
  • translate: Normally, a pipe character is put between a codon and an amino acid when the translated codon is identical to the amino acid.

Preposition: in

  • frame: The Rare Codon Display Rare codons in each reading frame are marked below the open reading frame plot.

Adjective modifier

  • premature: The second mutation introduces a premature stop codon in the mature protein 34.
  • rare: In both plots, the positions of rare codons are indicated by dots above each translation frame.
  • potential: Output Potential start codons are written only in lowercase letters.
  • possible: The output table is a file with the sum of all the observations for each of the 64 possible codons.
  • first: We recommend that gene sequences be numbered so that the first base of the first codon is numbered zero.

Modifies a noun

  • usage: This is called the ' codon usage ' of the organism.
  • frequency: You also can create or modify a codon frequency table with a text editor.
  • preference: Helps identify genes when you do not have specific knowledge of codon preference.
  • bias: The human genes were extensively adjusted for codon bias.
  • table: You also can create or modify a codon frequency table with a text editor.
  • statistic: ACKNOWLEDGMENT [ Previous | Top | Next ] The codon preference statistic comes from Gribskov et al.

Noun used with modifier

  • initiation: The coding region begins with the initiation codon, which is normally ATG.
  • termination: It ends with one of three termination codons: TAA, TAG or TGA.
  • stop: The second mutation introduces a premature stop codon in the mature protein 34.
  • start: Mark start codons - color can be changed in the options file.
  • translation: The glycoprotein gene has a translation stop codon in the middle of it, preventing the synthesis of the full length protein.
