The mitochondria of brown adipocytes have a unique protein in their inner membrane, Thermogenin (uncoupling protein 1 ), provides a path for protons to return to the matrix without passing through the FoF1 complex.

In G-banding, chromosomes are first gently heated and then exposed to Giemsa stain; this DNA dye preferentially darkens certain regions to produce alternating dark and light G bands. Each G band is a very large segment of DNA from 1 to 10 Mb in length, containing many loops. With high-resolution G-banding techniques, a standard diploid human karyotype of 46 chromosomes is seen to contain hundreds of dark and light G bands. Not used in plants.
