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 of the 20 different amino acids is specified by three-letter words of genetic code (called codons) that make up the mRNA nucleotide sequence. Ribosomes translate mRNAs at an amazing rate of up to 20 codons per second, and can do so over and over again, producing hundreds of copies of the corresponding protein.
