Expert Answer
1. Actin and myosin are proteins which play a significant role in muscle contraction. Cyclosis refers to the streaming of cytoplasm inside a living cell. This motion enables materials to reach all parts of a cell including oxygen and nutrients.
2. Nucleolar organizer region or NOR is a region in the chromosome around which the nucleolus forms. It contains genes for ribosomal RNA.
