The nucleus is the largest organelle in eukaryotic cells and its dynamics has an important role in different cell functions such as cell migration. In the last few years, studies have underlined the importance of accurately positioning nuclei within cell for cell migration. The first studies were ...
Learn about different cell organelles and their functions, including an organelle function chart and illustrations. Related to this QuestionThe cell organelle in which most of the ATP synthesis occurs is the: a) nucleus. b) plasma membrane. c) ...
A cell is a complex unit that performs several complex functions. An organelle is a specialized subunit within a cell that fulfills a specific role or function. Organelles are enclosed within their own lipid bilayers or are unbound by membranes. If a cell is viewed as an organism, the organ...

The origin of the eukaryotic cell, which is known as eukaryogenesis, has puzzled scientists for more than 100 years, and many hypotheses have been proposed. Recent analyses of new data enable the safe elimination of some of these hypotheses, whereas support for other hypotheses has increased. ...
The primary origin of the chloroplast organelle (plastid) in all eukaryotic photosynthetic organisms lies in the ancient engulfment of a photosynthetic cyanobacterium by a heterotrophic eukaryote in a process termed primary endosymbiosis. Over time, most genes of the primary endosymbiont were lost or tra...
Subcellular organelles, despite their role in compartmentalizing the sub-organelle components at optimum; have been also identified to play an essential role in drug resistance [196]. After drug administration, the drug usually enters the cells to reach its targets which are mainly present in cellul...
Evolutionary transitions from maternal to paternal inheritance are not especially common, but do happen (Table1, Supplementary TableS1). Interestingly, shifts in one organelle do not always affect the other cytoplasmic elements within the cell (but seePelargonium(Weihe et al.2009);Sequoia(Neale et ...
Nuclear pore complexes are evolutionary chimaeras of endomembrane- and mitosis-related chromatin-associated proteins. The keys to understanding eukaryogenesis are a proper phylogenetic context and understanding organelle coevolution: how innovations in one cell component caused repercussions on others. ...
Dynactin is a large multisubunit protein complex that enhances the processivity of cytoplasmic dynein and acts as an adapter between dynein and the cargo. It is composed of eleven different polypeptides of which eight are unique to this complex, namely d
