Witryna9 lut 1996 · Every membrane-bordered organelle in a particular cell type has a characteristic copy number, size, and position, which reflect its cellular function. Mitochondria, for example, are often located near organelles that consume energy, and their number is determined by the magnitude of these energy needs. They are … WitrynaChapter 9 – Extranuclear Inheritance Chapter 9 Concepts Extranuclear inheritance occurs when phenotypes result from genetic influence other than the biparental transmission of genes located on chromosomes housed within the nucleus. Organelle heredity, an example of extranuclear inheritance, is due to the transmission of …
