In the organism’s DNA, you find that 31% of the DNA bases are cytosine. What percentage of the bases will be guanine? Explain how you came up with this number in complete sentences.You are investigating the DNA composition of an organism. In the organism’s DNA, you find that 27% of the DNA bases are cytosine. What percentage of the bases will be adenine? Explain how you came up with this number in complete sentences.319087586995Figure 100Figure 1Figure 1 to the right shows two objects. Object B was created inside Object A. Object B is an important structure required for protein synthesis. What are the two objects?What is the name of the process that created Object B? (Hint: the first part of protein synthesis)rightbottomFigure 200Figure 2Proteins are considered polymers? Why? (Hint: what are proteins made of?)After its formation in Object A, Object B (from Figure 1) leaves for another part of the cell to continue protein synthesis. This process is shown below (Figure 2) taking place at Object C. What is the name of this process show below? (Hint: the second part of protein synthesis.) Label the object from Figures 1 and 2.Name: ____________________________________ Period: ____ Date: __ /__ / __DNA Structure and Protein Synthesis W/S 2You are investigating the DNA composition of an organism. In the organism’s DNA, you find that 19% of the DNA bases are thymine. What percentage of the bases will be guanine?
