A pyrimidine always pairs with a purine, so half of the bases will be pyrimidines and half will be purines.

How do the base pairing rule relate to chargaffs rules?
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.
When purine base only pairs with a pyrimidine?
when a purine base only pairs with a pyrimidine
What is specific base pairing?
a pair of nitrogenous bases,consisting of a purine linked by hydrozen bonds to a pyrimidine that connects the complementary strands . the base pair are adenine,thymine,cytosine & guanine in DNA & uracil in place of thymine in RNA.
Constituents of DNA?
Components of DNA include purine bases and pyrimidine bases (which, when combined, make up base pairs), deoyribose sugars, nucleotides and nucleosides.
If DNA molecule is compared to a spiral staircase what part make up the steps?
pairs of nitrogen bases
A particular sequence of parent DNA has five purine bases and two pyrimidine bases. According to base pairing rules, which of the following sequences could be formed during replication?
Chargaff's rule means that there should be the same number of purine and pyrimidine bases in DNA. The base-pairing rules mean 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.
What is the order ofd the nitrogen bases?
Adenine pairs with Thymine(Double bond) Guanine pairs with Cytosine (Triple Bond) A & G are purine bases and T & C are pyrimidine bases.
