The correct Answer is:
To determine which of the following bases is not present in DNA, we can analyze each option provided: 1. **Adenine (A)**: Adenine is one of the four nitrogenous bases found in DNA. It pairs with thymine in the DNA structure. 2. **Thymine (T)**: Thymine is also one of the four nitrogenous bases present in DNA. It pairs with adenine. 3. **Cytosine (C)**: Cytosine is another nitrogenous base found in DNA. It pairs with guanine. 4. **Uracil (U)**: Uracil is not found in DNA. Instead, it is one of the nitrogenous bases found in RNA, where it replaces thymine. Based on this analysis, the base that is not present in DNA is **Uracil (U)**. ### Final Answer: Uracil is the base that is not present in DNA.
