Name Class Date Section Protein Synthesis pages 148-153) 7-3 SECTION REVIEW In this section you studied the process of pro- tein synthesis. You learned that the informa- tion that DNA transfers to messenger RNA (MRNA) is in the form of a code. When the information is decoded, chains of amino acids, called polypeptides, are formed. Polypeptides During translation, each MRNA codon in turn make up proteins, which direct biochemical pathways and are responsible for cell structure and movement. The genetic code is determined by the arrangement of the nitrogenous bases in DNA and RNA. A code word in DNA consists of a group of three nucleotides. When transcribed into MRNA, each code word, or codon, desig- nates a specific amino acid that is to be placed in the polypeptide chain. More than one codon may code for a particular amíno acid. The MANA sequence AUG serves as an initiator, or "start," codon. Three other…
