Yes. Adenine+Guanine, or Cytosine+Thymine; each is a pyrimidine/purine pair.
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.
Chargaff's rule means that there should be the same number of purine and pyrimidine bases in DNA. The base pairing rules means that A always pairs with T, and G always pairs with C ie. a purine always pairs with a pyrimidine, so there must be the same number of both proving Chargaff's rule.
Hydrogen bonds hold purine bases (adenine and guanine) and pyrimidine bases (cytosine, thymine, and uracil) together in DNA and RNA molecules. These hydrogen bonds form between specific pairs of bases, with adenine always pairing with thymine (or uracil in RNA) and guanine always pairing with cytosine.
When a purine base pairs with a pyrimidine, it forms a complementary base pair. This pairing is important in the structure of DNA molecules, where adenine pairs with thymine and guanine pairs with cytosine through hydrogen bonding, creating the double helix structure of DNA.
No, purines cannot pair with other purines in DNA or RNA. Purines always pair with pyrimidines through complementary base pairing to maintain the double-stranded structure of DNA. In DNA, adenine (a purine) pairs with thymine (a pyrimidine) and guanine (a purine) pairs with cytosine (a pyrimidine).

Based on the numebr of complementary hydrogen bonds. C (cytosine) bonds with G (guanine) through 3 hydrogen bonds whereas T (thymine) bonds with A (adenine) with only two.
Because the nucleotides are complementary (A-T and G-C)when adenine combines with thymine it is the same length as when guanine combines with cytosineThats why when there is incorrect base pairing the width is irregular (like A-C).
It has to do with the size of each molecule. One is large (double ring) and the other is small (single ring). By having them pair with each other, the spacing along the length of DNA or RNA is kept uniform.
Adenine(purine)=========thymine(pyrimidine)Guanine(purine)----------------cytosine(pyrimidine)
