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.
Eukaryotic cells are large, advanced and multicellular. They do contain membrane-bound organelles (plants contain a large vacuole and chloroplasts) and do have a distinct nucleus (the nucleus is surrounded by a nuclear membrane and the DNA is therefore cut off from the cytoplasm).hey do not contain any membrane-bound organelles (such as chloroplasts, mitochondria, endoplasmic reticulum, etc) and do not have a distinct nucleus (ie: no nuclear membrane-so the DNA is floating around in the cytoplasm).
