This is a basic principle of DNA base pairing called Chargaff's rule. Adenine (purine) pairs with thymine (pyrimidine), while guanine (purine) pairs with cytosine (pyrimidine). This complementary base pairing is essential for the double-stranded structure of DNA.
Cytosine and thymine are the pyrimidine bases in DNA.
A basic compound that contains nitrogen, such as a purine or pyrimidine. A basic compound that contains nitrogen, such as a purine or pyrimidine.
It is expected that the chemical will become reactive as it becomes basic. It may also react when it becomes acidic.
Thymine and cytosine are the pyrimidine bases of DNA. Uracil is the pyrimidine base which replaces thymine in RNA.
