Chapter 14 - Prokaryotic and organelle genetics. This chapter begins with a discussion of the origins of yeast mitochondrial work. It then discusses the development of Chlamydomonas reinhardtii as a model organism. It also shows how early work on the organelle genetics of Chlamydomonas and yeast were carried out relatively independently; but inevitably the rationales soon paralleled one another. | PowerPoint to accompany Genetics: From Genes to Genomes Fourth Edition Leland H.
