The "rungs" of the DNA molecule are composed of NITROGENOUS BASES.

The deoxyribonucleic acid (DNA) molecule is a double helix made up of two long chains of nucleotides.

In DNA, there are four types of nucleotides, each containing one of the four nitrogenous bases Guanine, Adenine, Cytosine and Thymine.

Nitrogenous bases in opposite strands are held together by hydrogen bonds, forming thus the rungs of the DNA molecule.

In conclusion, the "rungs" of the DNA molecule are composed of NITROGENOUS BASES.
