Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.

DNA 
allows  an organism or cell to synthesize proteins and to pass that cell's/organism's characteristic to future generations of both cells (mitosis) and offspring (meiosis)

theedwardsfamily · Answer

DNA is one of the nucleic acids, information-containing molecules in the cell (ribonucleic acid, or RNA, is the other nucleic acid). DNA is found in the nucleus of every human cell. The information in DNA: 
guides the cell (along with RNA) in making new proteins that determine all of our biological traits 
gets passed (copied) from one generation to the next
