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.
The nucleus holds the cell's DNA and controls all cell function. Cells with a nucleus are eukaryotic, and are also known as eukaryotes. However, not all cells have a nucleus. Some cells have their DNA just floating around the cell.
