Cytochrom c evolution
WebIn the early 1960s, a linear evolution of cytochromes was suggested by Emanuel Margoliash [7] that led to the molecular clock hypothesis. The apparently constant evolution rate of cytochromes can be a helpful tool in trying to determine when various organisms may have diverged from a common ancestor. [8] Types [ edit] WebCytochrome c is a protein found in mitochondria. It is used in the study of evolutionary relationships because most animals have this protein. Cytochrome c is made of 104 amino acids joined together. Below is a list of the amino acids in part of a cytochrome protein molecule for 9 different animals.
