Yes. Adenine+Guanine, or Cytosine+Thymine; each is a pyrimidine/purine pair.

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
How does DNA base pairing result in molecule that has uniform width?
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).
Draw and label a segment of DNA showing its helix and complementary base pairing?
If you're drawing a diagram, then it's best to look at other diagrams and models of DNA. Some are provided in the links below, although there is a wealth of information about DNA on the internet that can be found if searched for.
What is the diameter of the DNA double helix?
Purines always bond with Pyrimidines.

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?

What is transversion mutation?
in this a purine base is substitued in place or pyrimidine and a pyrimidine is substitued in place of purine

How are four bases paired in a molecule DNA?
Adenine(purine)=========thymine(pyrimidine)Guanine(purine)----------------cytosine(pyrimidine)
Is nitrogen a base?
A basic compound that contains nitrogen, such as a purine or pyrimidine. A basic compound that contains nitrogen, such as a purine or pyrimidine.
Why do the purine and pyrimidine bases always pair together?
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.
Where a purine base only pairs with a pyrimidine?
nitrogen
