Alkanes are an example of saturated compounds. An unsaturated compound is a chemical compound that contains carbon-carbon double bonds or triple bonds, such as those found in alkenes or alkynes, respectively.Saturated and unsaturated compounds need not consist only of a carbon atom chain.n unsaturated compound is a chemical compound that contains carbon-carbon double bonds or triple bonds, such as those found in alkenes or alkynes, respectively.

Mitochondria Have DNA. Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell. And both organelles use their DNA to produce many proteins and enzymes required for their function. A double membrane surrounds both mitochondria and chloroplasts, further evidence that each was ingested by a primitive host.
1 Mitochondria and Chloroplasts: generate energy for the cell. 2  Mitochondria are self-replicating organelles that occur in various numbers, shapes, and sizes in the cytoplasm of all eukaryotic cells. The eukaryotic DNA is organized in one or more linear molecules, called chromosomes, which are associated with histone proteins. 2  All chromosomal DNA is stored in the cell nucleus, separated from the cytoplasm by a membrane. 3  Some eukaryotic organelles such as mitochondria also contain some DNA.
