NEET BIOLOGY

Detailed explanation-1: -Before cell division, the centrosome duplicates and then, as division begins, the two centrosomes move to opposite ends of the cell. Proteins called microtubules assemble into a spindle between the two centrosomes and help separate the replicated chromosomes into the daughter cells.

Detailed explanation-2: -Centrioles help to arrange the microtubules that move chromosomes during cell division to ensure each daughter cell receives the appropriate number of chromosomes. Centrioles are also important for the formation of cell structures known as cilia and flagella.

Detailed explanation-3: -Centrioles are responsible for organizing the spindle fibers in the mitotic spindle apparatus and are thought to participate in the completion of cytokinesis during the process of cell division.

Detailed explanation-4: -What is the role of a centriole in a cell? The centriole is concerned with the cell division. They help in the formation of spindle fibres that separate the chromosomes during the cell cycle.

Detailed explanation-5: -Most centrioles are made up of nine circularly arranged triplet microtubules. A triplet microtubule has a complete microtubule (the A-tubule) onto which two additional partial microtubules are assembled (the B-and the C-tubules, respectively).
