Most of the mechanisms discussed thus far involve one or more additional components superimposed onto the basic machinery of organelle biogenesis in order to regulate size. However there is a class of models in which no additional control components need be invoked. Most organelles are dynamic, unde...
Bone Size In subject area: Social Sciences Bone size refers to the dimensions of bones, which can be quantified by measuring cortical thickness using radiographs, a method known as radiogrammetry. It is an important factor in assessing bone density and fracture risk in clinical practice and resea...
The formation and maintenance of subcellular structures and organelles with a well-defined size is a key requirement for cell function, yet our understanding of the underlying size control mechanisms is limited. While budding yeast cell polarization and

Given a list of organisms, organelles, molecules and atoms be able to rank them in terms of relative size. Which variable decreases as the cell grows, so that it sets a limit to the size of cells? Explain how a cell can make a variety of large molecules from a small set of molecules...
The most evolutionary significant cases of genome reduction may be the eukaryotic organelles that are derived from bacteria: the mitochondrion and plastid. These organelles are descended from endosymbionts, which can only survive within the host cell and which the host cell likewise needs for survival...
Mitochondria are highly specialized structures (organelles) within each nucleated cell. The number of mitochondria in a cell depends on the cell's function. Cells with particularly heavy energy demands, such as heart muscle cells, have more mitochondria than other cells. The mitochondria's primary ...
Therefore, in order to study all these interesting phenomena in a single model and find the most essential factors regulating these phenomena, a minimal but general model with as few parameters as possible should be developed. In this paper, we will focus on the size effects of mitotic ...
