<P> Within eukaryotic cells DNA is organized into long structures called chromosomes . During cell division these chromosomes are duplicated in the process of DNA replication , providing each cell its own complete set of chromosomes . Eukaryotic organisms ( animals , plants , fungi and protists ) store most of their DNA inside the cell nucleus and some of their DNA in organelles , such as mitochondria or chloroplasts . In contrast prokaryotes ( bacteria and archaea ) store their DNA only in the cytoplasm . Within the eukaryotic chromosomes , chromatin proteins such as histones compact and organize DNA . These compact structures guide the interactions between DNA and other proteins , helping control which parts of the DNA are transcribed . </P>
