Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is microtubule function?
A
Chromosomes movements
B
Cleavage furrow formation
C
Formation of nuclear lamina
D
None of the above
Explanation: 

Detailed explanation-1: -Microtubules are responsible for a variety of cell movements, including the intracellular transport and positioning of membrane vesicles and organelles, the separation of chromosomes at mitosis, and the beating of cilia and flagella.

Detailed explanation-2: -As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. The spindle tubules then shorten and move toward the poles of the cell. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell.

Detailed explanation-3: -Microtubules are part of the cytoskeleton, a structural network within the cell’s cytoplasm. The roles of the microtubule cytoskeleton include mechanical support, organization of the cytoplasm, transport, motility and chromosome segregation.
