c) Centrosome disassembly, spindle formation, chromosome separation, and microtubule depolymerization
d) Nuclear envelope formation, ribosome synthesis, DNA replication, and cell division

Answer 1

MTOCs control microtubule assembly, nucleation, anchoring, and organization.

Step-by-step explanation:

The major features controlled by MTOCs (Microtubule Organizing Centers) are:

1. Microtubule assembly: MTOCs nucleate the assembly of microtubules, which are essential for maintaining the cell's shape, providing support, and facilitating intracellular transport.
2. Nucleation: MTOCs act as the sites of microtubule nucleation, initiating the growth and organization of microtubules within the cell.
3. Anchoring: MTOCs anchor microtubules to specific locations in the cell, ensuring their stability and proper function.
4. Organization: MTOCs help organize microtubules into functional structures, such as the mitotic spindle, which is crucial for accurate chromosome segregation during cell division.
