Protein Synthesis & Genetic Engineering Test 1. At the beginning of this unit, we were introduced to a nucleic acid called ribonucleic acid,
or RNA for short. It plays an important role in protein synthesis. 1) Compare and
contrast the structure and function of RNA with DNA. 2) State the central dogma by
including DNA, RNA, and proteins into your statement. 3) Name the three main RNA
molecules introduced in this unit, and briefly explain their functions. 4) Explain what a
codon and amino acids are. (10 points)
