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.
When the mRNA code is read by the proteins that build the amino acid chain, it's not read as a sequence of individual letters. It's read in chunks of 3 letters, or 3 nitrogenous bases, at a time. Each set of 3 bases is a special code that indicates a different amino acid.The 3-base sets are called codons. codon is a series of 3 bases in mRNA that specifies a particular amino acid. Codons can also indicate a stop, or termination signal, but we'll get to that in a minute. For now, just think of codons as the basic unit for the genetic code.
