Final answer:
Deoxyribonucleic acid (DNA) is the macromolecule responsible for storing genetic information, containing the instructions for the growth and function of living organisms. It is located in the nucleus of eukaryotic cells and also in cell organelles like mitochondria and chloroplasts.
Step-by-step explanation:
The macromolecule that stores our genetic information is deoxyribonucleic acid (DNA). DNA is comprised of long chains of nucleotides, which encode the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms. As a key component of the continuity of life, DNA carries the genetic blueprint of a cell along with the necessary information to conduct the cell's functions.
DNA is found in the nucleus of eukaryotic cells, and also in the mitochondria and chloroplasts, with a simplified version present in prokaryotic cells not enclosed in a nucleus. Together with ribonucleic acid (RNA), DNA is essential in the synthesis of proteins and the transfer of genetic material from one generation to the next.
