DNA is a double helix consisting of two strands orientated in an _antiparallel_ configuration meaning the 5' to 3' direction of one strand runs counter to direction of the other strand.
DNA is a nucleic acid.
Nucleic acids are linear polymers composed of nucleotides joined by their extremes.
Nucleotides are monomers composed of
Nitrogenated bases are adenine, guanine, cytosine, and thymine
These nucleotides together compose a strain or a helix.
A DNA molecule is composed of two parallel strains.
The bases of each strain pair the bases of the other strain,
The direction of these strains in the molecule is opposite to each other, which means that they are antiparallel to each other.
