two types of macromolecules: nucleic acid and protein

Explanation:

Chromosomes particularly eukaryotic chromosomes are made up of nucleic acids in particular DNA (deoxyribonucleic acid) and some proteins which include histone proteins and non histone protein that helps in the packaging of an almost 2m DNA into a very tiny 0.6microm nucleus. The histone protein includes H2A, H2B, H3, H4 which forms an octamer around which the DNA is wrapped (structure of a nucleosome) and linker histone H1 joined to a linker DNA that links two nucleosomes.
