more than 4 chemicals make it up but the 4 nitrogen bases are adinine guanine cytosine and thymine
The two chemicals that make up the rungs of the DNA ladder are adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C). These base pairs connect the two strands of the DNA double helix together.

This means the two strands of DNA are complementary.
DNA strands are packed into structures called chromosomes. Chromosomes are made up of long strands of DNA that are tightly coiled and condensed to fit inside the nucleus of a cell.
In a DNA molecule, two polynucleotide strands are present. These strands are arranged in a double helix structure, with each strand consisting of a sequence of nucleotides that are complementary to each other.

DNA is made up of two strands.
To make correct proteins for the body.

A deoxyribose sugar and phosphate groups.

Chromatins are made up of DNA strands
There is no such thing called a DNA nucleus. I assume you mean DNA found in the nucleus. The DNA that's found in the nucleus are many DNA strands all bunched up.
Hydrogen bonding infers that the two strands are VERY close together so the strands are practically right next to each other. As the strands wind up in a larger scale they wrap around proteins to keep them secure and finally form a combined material called chromatin which make up chromosomes in eukaryote cells.
