Explain each option.... In detail..
Dear student,
Answer is a) adenine has 4 nitrogen atoms
Adenine is a purine with two rings. It contains 4 nitrogen at position 1, 3, 7 and 9.
Cytosine is a pyrimidine with single ring structure containing 2 nitrogen at position 1 and 3
Guanosine is a purine containing 4 nitrogen at position 1, 3, 7 and 9
Uracil is a pyrimidine containing 2 nitrogen at position 1 and 3
