  1. Codon | Definition, Function, & Examples | Britannica

    codon, in genetics, any of 64 different sequences of three adjacent nucleotides in DNA that either encodes information for the production of a specific amino acid or serves as a stop signal to …

  2. Codon Chart: Table, Amino Acids & RNA Wheel Explained

    Dec 11, 2024 · Explore the codon chart, tables, amino acids, and RNA wheel. Learn how to read and interpret codons for protein synthesis and genetic coding.

  3. Genetic code - Wikipedia

    Genetic code is a set of rules used by living cells to translate information encoded within genetic material (DNA or RNA sequences of nucleotide triplets or codons) into proteins.

  4. Codon - National Human Genome Research Institute

    3 days ago · A codon is a DNA or RNA sequence of three nucleotides (a trinucleotide) that forms a unit of genomic information encoding a particular amino acid or signaling the termination of protein …

  5. Codon - Definition and Examples - Biology Online Dictionary

    Jul 24, 2022 · Because the collection of codons on mRNA forms the genetic code, a codon is the smallest unit of genetic code. In simple terms, each codon actually encrypts a specific amino acid. It …

  6. What Is a Codon? The Genetic Code Explained - ScienceInsights

    Nov 7, 2025 · A codon is defined as a sequence of three nucleotides found on the messenger RNA molecule. These nucleotides are the building blocks of RNA—Adenine (A), Uracil (U), Cytosine (C), …

  7. What is a Codon? Unlocking the Genetic Language of Life

    Apr 27, 2025 · At the very core of this biological language lies the concept of the codon —a small, three-letter word written in the alphabet of nucleotides. Although each codon is made of just three simple …

  8. Definition of codon - NCI Dictionary of Genetics Terms

    Certain codons signal the start or end of translation. These are called start or stop (or termination) codons. Transcription and translation are processes a cell uses to make all proteins the body needs …

  9. Codons | Biology for Majors I - Lumen Learning

    These nucleotide triplets are called codons. The insertion of one or two nucleotides completely changed the triplet reading frame, thereby altering the message for every subsequent amino acid (Figure 1).

  10. What Is a Codon in DNA and How Does It Build Proteins?

    Dec 1, 2025 · A codon is a sequence of three consecutive nucleotide bases that specifies a single amino acid or serves as a regulatory signal. DNA and RNA are built from four distinct bases: Adenine, …
