Various membrane-bound organelles (MBOs) with diverse activities achieve their function
by compartmentalization and regulate them in a spatiotemporal manner. On the other hand,
a new class called membrane-less organelles (MLOs) or condensates have been
discovered to be assembled via a liquid–liquid phase separation process. Phase separation
has been observed previously in synthetic polymers but now appears to be relevant to cells
too. In this chapter, we focus on the MBOs and MLOs and their biogenesis. The factors …
