Adenine has the highest number of nitrogen atoms. Its chemical name is 6-amino purine. A purine ring has 4 nitrogen atoms and additionally there is one amino group. Hence, total 5 nitrogen atoms. While cytosine has 3 nitrogen atoms, uracil and thymine have 2 nitrogen atoms each. The number of nitrogen atoms in Guanine is also 5 (not given in option).

Which of the following nitrogen bases has the highest number of nitrog...
Explanation:
The nitrogen bases are one of the building blocks of nucleic acids, which include DNA and RNA. There are four nitrogen bases found in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, thymine is replaced by uracil (U). Each nitrogen base has a different structure and composition.
Nitrogen atoms in adenine (A):
Adenine is a purine base, which means it has a double-ring structure. It consists of two carbon-nitrogen rings, each containing two nitrogen atoms. Therefore, adenine has a total of four nitrogen atoms.
Nitrogen atoms in cytosine (C):
Cytosine is a pyrimidine base, which means it has a single-ring structure. It contains only one nitrogen atom in the ring.
Nitrogen atoms in uracil (U):
Uracil is also a pyrimidine base, similar to cytosine, and it contains only one nitrogen atom in the ring.
Nitrogen atoms in thymine (T):
Thymine is also a pyrimidine base and shares a similar structure with uracil. It also contains only one nitrogen atom in the ring.
Comparison:
- Adenine (A) has the highest number of nitrogen atoms, with four in total.
- Cytosine (C), uracil (U), and thymine (T) each have only one nitrogen atom.
Conclusion:
Based on the above comparison, it is evident that adenine (A) has the highest number of nitrogen atoms among the four nitrogen bases.
