4. 11 th Grade Science On our practice ACT, 25% of your classmates answered this correctly. 2. According to the Protein Hypothesis, which of the following observations provides the strongest evidence that genes are NOT composed of DNA? A. DNA is composed of only 4 types of nucleotides. B. DNA is composed of smaller subunits than are proteins. C. DNA is abundant in both the nucleus and the cytoplasm. D. The concentration of DNA is generally consistent from cell to cell.

5. 11 th Grade Science On our practice ACT, 28% of your classmates answered this correctly. 3. Mitochondria are organelles located in the cytoplasm that are responsible for energy transformation in a cell. After the 1940s, it was observed that mitochondria contain their own genes. This observation contradicts evidence stated in which hypothesis? A. The DNA Hypothesis, because if genes are made of DNA, the observation would show that DNA is present outside the nucleus. B. The DNA Hypothesis, because if genes are made of DNA, the observation would show that DNA is present inside the nucleus. C. The Protein Hypothesis, because if genes are made of proteins, the observation would show that proteins are present outside of the nucleus. D. The Protein Hypothesis, because if genes are made of proteins, the observation would show that proteins are present inside the nucleus.

6. 11 th Grade Science On our practice ACT, 29% of your classmates answered this correctly. 4. The scientist who describes the DNA Hypothesis implies that the Protein Hypothesis is weakened by which of the following observations? A.For a given organism, the amount of protein in the gametes is half that found in other types of cells. B.For a given organism, the amount of protein in different types of cells is not the same. C.Protein molecules are composed of many subunits. D. Proteins are found only in the nucleus.
