Final answer:
The difference in bonding between adenine-thymine and guanine-cytosine is the number of hydrogen bonds and the structure of the bases. Adenine-thymine pairs form two hydrogen bonds and guanine-cytosine pairs make three. Also, adenine and guanine are purines while thymine and cytosine are pyrimidines.
Step-by-step explanation:
The difference between the bonding of adenine (A) and thymine (T) and the bonding of guanine (G) and cytosine (C) lies in the number of hydrogen bonds and the structure of these bases. Both A and T, and G and C are car complemented pairs and form bonds using the principle of base-pairing - explained in Christians rules. However, there is a significant difference which is adenine and thymine form two hydrogen bonds between them while guanine and cytosine form three. Additionally, adenine and guanine are categorized as purines, characterized by their double-carbon nitrogen rings, and thymine and cytosine are known as pyrimidines, which possess single-carbon nitrogen rings.
