Why does cytosine not form a bond with adenine?

سائٹوسین ایڈنائن کے ساتھ بانڈ کیوں نہیں بناتا؟

Cytosine is unable to form hydrogen bonds with adenine.

Adenine and cytosine have incompatible hydrogen bond donors and acceptors.

Cytosine only pairs with thymine due to their complementary structures.

Adenine is a pyrimidine and cannot bond with cytosine.

Cytosine does not form a bond with adenine because its hydrogen bond donors and acceptors are not complementary.

Cytosine typically forms three hydrogen bonds with guanine, whereas adenine forms two hydrogen bonds with thymine.

The patterns of hydrogen bonding in cytosine and adenine do not match, preventing the formation of a stable pair.
