DNA Facts #1

  • The chromosomes in the nucleus of a cell contain all the information a cell needs to carry on its life processes. They are made up of a complex chemical called deoxyribonucleic acid (DNA).

  • DNA is the hereditary material of all cells. It is a double-stranded helical macromolecule.

  • DNA occurs as fine, spirally coiled threads that in turn coils around another, like a twisted ladder.

  • If stretched out, would form very thin thread, about 2 meters (over 6 ft) long.
