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 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 کاملMitochondrial membrane potential: a trait involved in organelle inheritance?
Which mitochondria are inherited across generations? Are transmitted mitochondria functionally silenced to preserve the integrity of their genetic information, or rather are those mitochondria with the highest levels of function (as indicated by membrane potential Δψm) preferentially transmitted? Based on observations of the unusual system of doubly uniparental inheritance of mitochondria and o...
متن کاملSharing the cell's bounty - organelle inheritance in yeast.
Eukaryotic cells replicate and partition their organelles between the mother cell and the daughter cell at cytokinesis. Polarized cells, notably the budding yeast Saccharomyces cerevisiae, are well suited for the study of organelle inheritance, as they facilitate an experimental dissection of organelle transport and retention processes. Much progress has been made in defining the molecular play...
متن کاملSpatiotemporal analysis of organelle and macromolecular complex inheritance.
Following mitosis, daughter cells must inherit a functional set of essential proteins and organelles. We applied a genetic tool to simultaneously monitor the kinetics and distribution of old and new proteins marking all intracellular compartments in budding yeasts. Most organelles followed a general pattern whereby preexisting proteins are symmetrically partitioned followed by template-based in...
