Organelle Inheritance
The need to inherit those membranes that arise from the ER is much less clear. As an example, the integral *Imperial Cancer Research Fund Cell Biology Laboratory membrane proteins and lipids of the Golgi apparatus are derived entirely from the ER. If a daughter did not 44 Lincoln's Inn Fields London WC2A 3PX inherit a copy of the Golgi apparatus, it should be able to synthesize one de novo. Sev...
متن کاملMechanisms of organelle division and inheritance and their implications regarding the origin of eukaryotic cells
Mitochondria and plastids have their own DNAs and are regarded as descendants of endosymbiotic prokaryotes. Organellar DNAs are not naked in vivo but are associated with basic proteins to form DNA-protein complexes (called organelle nuclei). The concept of organelle nuclei provides a new approach to explain the origin, division, and inheritance of organelles. Organelles divide using organelle d...
متن کاملUniparental inheritance of organelle genes
the remarkable and varied molecular and cellular mechanisms that produce these patterns. I will also consider the evolutionary consequences of uniparental inheritance and some of the proposed evolutionary explanations for this remarkable difference between the inheritance of organelle and nuclear genes. Patterns and mechanisms of uniparental inheritance vary widely Correns studied the four-o'cl...
متن کاملCytoplasmic inheritance redux.
Since the early twentieth century, inheritance was seen as the inheritance of genes. Concurrent with the acceptance of the genetic theory of inheritance was the rejection of the idea that the cytoplasm of the oocyte could also play a role in inheritance and a corresponding devaluation of embryology as a discipline critical for understanding human development. Development, and variation in devel...
متن کاملMaternal Cytoplasmic Inheritance
We explicitly solve and analyze a series of deterministic continent-island models to delimit the effects of pollen and seed migration on cytonuclear frequencies and disequilibria in random-mating, mixed-mating and self-fertilized populations. Given the critical assumption of maternal cytoplasmic inheritance, five major findings are (i) nonzero cytonuclear disequilibria will be maintained in the...
