WebDNA is the molecule that carries the genetic instructions for life. It is composed of two strands of nucleotides that coil around each other to form a double helix. You will recall that bacteria, or prokaryotes, are cellular organisms that lack both a nucleus to contain their DNA and membrane-bound organelles.

WebProkaryotic cells can be distinguished from eukaryotic cells by the absence of a well-defined nucleus. However, their negatively charged DNA is arranged in a region called the nucleoid. They appear as a loop wrapped around a protein molecule having a positive charge. All eukaryotes have a well-defined nucleus that contains DNA.
