Adenine can only pair with thymine and cytosine can only pair with guanine due to their complementary base pairing in DNA. Adenine and thymine form two hydrogen bonds between them, while cytosine and guanine form three hydrogen bonds. This specific pairing is essential for maintaining the double-stranded structure of DNA and ensures the accurate replication and transmission of genetic information during cell division. The hydrogen bonding between these base pairs provides stability to the DNA molecule. **
