Just as a construction crew uses blueprints to build a house, a cell uses DNA as plans for building proteins. In addition to DNA, another nucleic acid, called RNA, is involved in making proteins. In the RNA and Protein Synthesis Gizmo, you will use both DNA and RNA to construct a protein out of amino acids. DNA is composed of the bases adenine (A), cytosine (C), guanine (G), and thymine (T). RNA is composed of adenine, cytosine, guanine, and uracil (U). Look at the SIMULATION (or image above) pane. Is the displayed segment a part of a DNA or RNA molecule? Question 1 options: DNA
RNA
