The most crucial macromolecules for maintaining life are nucleic acids. They contain instructions for a cell's proper operation as well as the genetic code for that cell.
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are the two primary forms of nucleic acids. All living things, from single-celled bacteria to multicellular mammals, have DNA as their genetic makeup. It is located in the organelle, chloroplasts, and mitochondria as well as the nuclei of eukaryotes. Prokaryotes lack a membranous sheath around their DNA. A cell's genome is its entire genetic makeup, and genomics is the study of genomes. DNA and histone proteins combine to form a complex to create chromatin, the material that makes up eukaryotic chromosomes, in eukaryotic cells yet not in prokaryotes. There may be hundreds or thousands of genes on a chromosome. Many genes encode for the production of protein molecules, while some genes produce RNA. DNA manipulates the genes to turn on or turn off various biological processes.
