in dna, the amount of adenine is always equal to the amount of
a) cytosine.
b) uracil.
c) guanine.
d) thymine.
e) atp.

Explanation:

According to Chargaff's rules in DNA, adenine pairs with thymine through hydrogen bonds. So, the amount of adenine is always equal to the amount of thymine. Cytosine pairs with guanine. Uracil is in RNA, not DNA. ATP is adenosine triphosphate, not a nitrogenous base in DNA base - pairing.

Answer:

d) thymine
