The correct Answer is:
To solve the question "All transformed cells contain," we will analyze the options provided and determine which one is correct based on our understanding of transformed cells. ### Step-by-Step Solution: 1. **Understanding Transformed Cells**: - Transformed cells are cells that have undergone a change that allows them to grow uncontrollably or have altered characteristics compared to normal cells. This transformation can occur due to various factors, including genetic modifications. 2. **Analyzing the Options**: - **Option A: C, DNA** - This refers to circular DNA typically found in prokaryotes. It is not specifically associated with transformed cells. - **Option B: Z, DNA** - This is not a recognized form of DNA in the context of transformed cells. - **Option C: R, DNA** - This stands for recombinant DNA, which is DNA that has been artificially formed by combining constituents from different organisms. While transformed cells may involve recombinant DNA, it is not the defining characteristic of all transformed cells. - **Option D: T, DNA** - This stands for transformed DNA. Transformed cells specifically contain T, DNA, which is a key characteristic of their transformation. 3. **Conclusion**: - After analyzing all the options, the correct answer is **Option D: T, DNA**. All transformed cells contain T, DNA, which is indicative of their altered state. ### Final Answer: All transformed cells contain **T, DNA**. ---
