Answer: DNA molecules is packaged into chromosomes which are found in the cell nucleus.
Explanation: Chromosomes are made up of DNA (deoxyribonucleic acid) coiled around proteins called histones that support its structure. In humans cells there are 23 pairs of chromosomes, that makes a total of 46. Twenty-two of those pairs are autosomes while the 23rd pair is called sex chromosomes.
The genetic information is stored in the structure of the DNA, so this molecule is the hereditary material in almost all living organisms. That is why it contains the instructions to construct components of the cell.
