Mitochondrial genes mutate much faster than those in the nucleus because of the free radicals produced in their energy-generating role. This high mutation rate lies behind our ageing and certain congenital diseases.
What gives us our energy, is behind the origin of two sexes, and directs our ageing and death? The answer in each case lies in mitochondria. Mitochondria are. Buy Power, Sex, Suicide: Mitochondria and the Meaning of Life on ykoketomel.ml ✓ FREE SHIPPING on qualified orders.
The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer, through their involvement in precipitating cell suicide. Mitochondria, then, are pivotal in power, sex, and suicide. In this fascinating and thought-provoking book, Nick Lane brings together the latest research findings in this exciting field to show how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose why don't we just bud?
Steven Pinker. Mitochondrial genes mutate much faster than those in the nucleus because of the free radicals produced in their energy-generating role. Seven Brief Lessons on Physics. Mitochondria are tiny structures located inside our cells that carry out the essential task of producing energy for the cell. Zoom Zoom. Life on the Edge.
This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death. The book abounds with interesting and important ideas.

Clock of life: Why mitochondria kill us in the end. There are hundreds of them in each cell, some 10 million billion in a human being. Once considered menial slaves, mere workhorses for complex cells with nuclei, their significance is now undergoing a radical revision. Mitochondria are now seen as the key ingredient that made complex life possible at all.
For two billion years, bacteria ruled the earth without ever generating true complexity - a stasis that may still grip life on other planets.
Then the union of two bacterial cells led to an evolutionary big bang, from which algae, fungi, plants and animals emerged. For mitochondria were once free-living bacteria, and still retain unmistakable traits of their ancestry, including some of their original DNA. Ever since their fateful absorption, the tortuous and unpredictable relationship between the mitochondria and their host cells has forced one evolutionary innovation after another.
Without mitochondria, nothing would exist of the world we know and love. Their story is the story of life itself. Today, mitochondria are central to research into human prehistory, genetic diseases, cell suicide, fertility, ageing, bioenergetics, sex and the eukaryotic cell. Piecing together puzzles from the forefront of research, this book paints a sweeping canvas that will thrill all who are interested in biology, while also contributing to evolutionary thinking and debate.
This is a book full of startling insights into the nature and evolution of life, and should be read by anyone who wants to know why we're here. Subject Mitochondria. Mitochondrial DNA.
