What is DNA?

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.

Where is DNA Found?

Within eukaryotic animal cells, DNA is located in the nucleus in organized structures called chromosomes.

Here the DNA is stained blue in a microscope view of a type of cells called HeLa cells. As you can see, the DNA is located in a area of the cell called the nucleus.
