Actin‚ a globular protein with a molecular weight of 42-kDa‚ is the most abundant intracellular protein in most eukaryotes (3). It plays important roles in many essential cell biological processes. Actin exists as a monomer called G-actin and as a filament called F-actin‚ a linear chain of G-actin subunits (2). Two F-actin filaments intertwine to form a microfilament‚ one of the three major components of cytoskeleton (2). Microfilament is important for generating cell movement. One mechanism involves

Do different brands of deodorants contain different amounts of aluminum? Thus‚ how can we stay on the safe side and use the least amount of aluminum possible. Why do deodorants with a greater amount of aluminum cause a more serious threat than ones with a smaller amount?

Animal Cell Organelles & Their Functions 1. Nucleus - The nucleus generally contains the genetic material for the cell. Because it contains the DNA and chromosomes‚ which affect the proteins that determine the activities of the cell‚ the nucleus can be considered to be the cell’s control centre. 2.
