The way in which the proteins that promote microfilament disassembly during cell shape changes distinguish newly synthesized microfilaments from older microfilaments. Concept introduction: Cytoskeleton is comprised of a system of protein filaments of three types, microfilaments, intermediate filaments, and microtubules. Thread-like protein fibers of 3-6 nm in diameter are called microfilaments . Actin, a major cellular protein predominantly makes up the microfilaments. They are contractile in nature. The functions of microfilaments include muscle contraction, variations in cell shape, cytokinesis during cell division, and streaming of the protoplasm, cell motility in the case of pseudopodia and cleavage furrow formation during cell division.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
