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.
First, the DNA code is copied on to the mRNA (messenger RNA) codon. A codon is a sequence of three nitrogenous bases. This process is called transcription. This mRNA codon is then carried from the nucleus out to the ribosome.Messenger RNA attaches to another kind of RNA called tRNA (transfer RNA).hree different types of RNA exist, mRNA or messenger RNA, tRNA or transfer RNA, and rRNA or ribosomal RNA. Protein Synthesis Cells store and use coded information. The genetic information stored in DNA is used to direct the synthesis of the thousands of proteins that each cell requires.
