Histones are proteins which are associated with DNA and from nucleosomes, which pack the DNA.
Transcription factors, proteins involved in DNA synthesis, replication...
The DNA in a single cell would be about 2m in length if stretched from end to end. To fit all of this into a cell the DNA has to be compacted. It is wound around proteins called histone, and these bundles are continually wound to form the chromosomes you can see under a microscope.
DNA is not catalytic so, as it is only a recipe for proteins, it needs proteins to carry out all the catalytic functions, such as replication. Also DNA needs to have its enormous length wrapped around many histone proteins. RNA is catalytic though.

Proteins are found in cells. Proteins are a macromolecule.

DNA is not composed of cells. Cells do have DNA inside them. DNA is however made up of various proteins and those are Guanine, Cytosine, Thymine, and Adenine

They don't belong to a kingdom because they are not cells. They are just genetic material wrapped in proteins that reproduce inside of cells.
