Similar filament-forming myosin proteins were found in cardiac muscle, smooth muscle, and nonmuscle cells. However, beginning in the 1970s, researchers began to discover new myosin genes in simple eukaryotes encoding proteins that acted as monomers and were therefore entitled Class I myosins. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell. Phases of meiosis II | Cells | MCAT | Khan Academy. 34 related questions found.
