Where are chromosomes located? in nucleic acids in ribosomes in the nucleus

nucleus

Explanation:

Chromosomes are structures composed of DNA that, in turn, carry the genes of a living being, responsible for defining the particular physical characteristics of each individual.

Chromosomes are located in the nucleus of the cells that make up the living being. Human beings have 46 chromosomes, divided into 23 pairs, of which 44 are autosomes and 2 are sexual.

The chromosomes that form pairs are called homologous and are called diploid cells (2n).

All the genetic information of a given individual, such as hair color, eye color, physical structure, and other hereditary characteristics, are present in the person's DNA. Chromosomes serve to store all this information, condensing the genetic material so that it fits inside the cells.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
