The following points highlight the top three filamentous structures of eukaryotic cell. The filamentous structures are: 1. Actin Filaments 2. Microtubules 3. Intermediate Filaments. Filamentous Structure # 1. Actin Filaments: a. The G-actin protein of non-muscle cells has a molecular weight of about 43,000 and contains N-methylhistidyl residues. b. This actin spontaneously polymerizes in the presence of magnesium and potassium [...]
