Base Pairing
The rules of base pairing (or nucleotide pairing) are:
A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T)
C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G) ...

Two nitrogenous (purine or pyrimidine) bases (adenine and thymine or guanine and cytosine) held together by weak hydrogen bonds. Two strands of DNA are held together in the shape of a double helix by the bonds between base pairs.

Wobble base pair
A wobble base pair is a G-U and I-U / I-A / I-C pair fundamental in RNA secondary structure. It has comparable thermodynamic stability of the Watson-Crick base pair.

Base Pair: Two nitrogenous bases held together by weak bonds. In a DNA molecule adenine always pairs with thymine while cytosine always pairs with guanine. Thus, one DNA strand directs the synthesis of the other strand.

Base Pair (bp): One pair of complementary nucleotides within a duplex strand of a nucleic acid. Under Watson-Crick rules, these pairs consist of one pyrimidine and one purine: i.e., C-G, A-T (DNA) or A-U (RNA). However, "noncanonical" base pairs (e.g.

DNA base pairing
Contrary to a common misconception, the DNA is not a single molecule, but rather a pair of molecules joined by hydrogen bonds: it is organized as two complementary strands, head-to-toe, with the hydrogen bonds between them.

Since G-C base pairs are more dense that A-T base pairs, the density of DNA increases as the % GC content increases.
