DNA is one of the nucleic acids along with RNA, it is made up of repeating nucleotides.
Each nucleotide is made up of a pentose sugar deoxyribose, a phosphate group, and a nitrogen-containing base (adenine, guanine, thymine, and cytosine).
DNA is called deoxy because of the absence of the hydroxyl group on the 2' carbon of the ribose.
All living organisms contain either DNA or RNA as their genetic material.
DNA plays a major role in each stage of an organism it may be in growth and development or reproduction.
They are the hereditary material in a cell that passes genetic information from parents to offspring.
Examples of organisms that contain DNA as genetic material: are plants, animals, and humans.
Examples of organisms that contain RNA as genetic material: are viruses like orthomyxoviruses, human immunodeficiency virus, and coronavirus.
