Codon and Anticodon

Everything about plants and animals is defined by a series of information in DNA and RNA. The information is laid out in RNA or DNA strand in a characteristic sequence for each living organism. The nitrogenous base arrangement is the information system in RNA and DNA, where these bases (Adenine, Thymine, Uracil, Cytosine and Guanine) offer unique sequence to make characteristic proteins that have unique shapes. Those proteins define the characters and traits of the living organisms. Proteins are made from amino acids. Each amino acid has a three-base unit that is well-matched with the bases in nucleic acid strands. If one of these base threesomes is the codon, the other is the anticodon.

A codon is a grouping of three consecutive nucleotides in a RNA or DNA strand. All the RNA and DNA have nucleotides sequence as codons. A nucleotide has one of A, C, T/U, or G. The three consecutive nucleotides consist of a sequence of nitrogenous bases that determines the compatible amino acid during protein synthesis.

Anticodon is the arrangement of nitrogenous bases in tRNA which is attached to amino acids. It is the equivalent nucleotide sequence to the codon in mRNA. They are attached to amino acids and determine the amino acid that binds to the synthesizing protein strand next.
