Cytosine pairs with guanine due to their specific hydrogen bonding patterns and structural compatibility in the DNA double helix. Cytosine has three hydrogen bond donors and acceptors that match with guanine's corresponding sites, ensuring stable base pairing. This complementary pairing is essential for the integrity of genetic information during DNA replication and transcription, maintaining the fidelity of genetic coding.
cytosine (C).
Guanine and cytosine always pair together due to specific hydrogen bonding interactions that stabilize their association in the DNA double helix. This base pairing rule is known as Chargaff's rule, where the amount of guanine is always equal to the amount of cytosine in a DNA molecule.
Guanine always pairs with cytosine
Nucleotides are the building blocks of DNA, consisting of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). They are linked together through phosphodiester bonds to form the DNA double helix structure.

cytosine pairs with guanine and thymine pairs with adenine.

Guanine
Guanine and cytosine always pair together due to specific hydrogen bonding interactions that stabilize their association in the DNA double helix. This base pairing rule is known as Chargaff's rule, where the amount of guanine is always equal to the amount of cytosine in a DNA molecule.
DNA bases match up in a specific way - adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This is known as complementary base pairing and ensures that DNA strands can replicate accurately.
Guanine always pairs with cytosine
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
Nucleotides are the building blocks of DNA, consisting of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). They are linked together through phosphodiester bonds to form the DNA double helix structure.
