Answers
GPT-4o mini
The four kinds of nitrogen bases that make up nucleotides in DNA and RNA are:
1. **Adenine (A)** - A purine base found in both DNA and RNA.
2. **Thymine (T)** - A pyrimidine base found in DNA (not found in RNA; in RNA, it's replaced by uracil).
3. **Cytosine (C)** - A pyrimidine base found in both DNA and RNA.
4. **Guanine (G)** - A purine base found in both DNA and RNA.
In summary, the nitrogen bases in DNA are adenine, thymine, cytosine, and guanine, while in RNA, uracil replaces thymine.
