Here's a little more detail:

* DNA structure: DNA is a double helix, meaning it consists of two strands that wrap around each other.

* Nucleotides: Each strand is made up of nucleotides, which are composed of a sugar (deoxyribose), a phosphate group, and a nitrogenous base.

* Base pairing: The nitrogenous bases on the two strands pair up specifically: adenine (A) with thymine (T), and guanine (G) with cytosine (C).

* Hydrogen bonds: These specific base pairs are held together by hydrogen bonds, which are weak but numerous, providing stability to the DNA double helix.
