a group of three mRNA nucleotides is called a codon, which meets complementary triplet of tRNA nucleotides, called an anticodon, in the ribosomes. Carboxyl(also called acid), amino, and the radical which is what is changed to make an amino acid unique.
Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assembleâin orderâthe chain of amino acids that form a protein.
