Answer

DNA = Deoxyribonucleic Acid

  • Deoxy = deoxyribose sugar (one oxygen fewer than ribose)
  • Ribo = ribose sugar backbone
  • Nucleic = found in the cell nucleus
  • Acid = acidic due to phosphate groups

DNA is a double-stranded helix carrying genetic instructions for all known living organisms.

Compare: RNA = Ribonucleic Acid single-stranded, helps translate DNA into proteins.

DNA stands for Deoxyribonucleic Acid the double-stranded molecule that carries all genetic information in living organisms.
