उत्तर
The centrosome is an area in the cell where microtubules are produced. Within an animal
cell centrosome, there is a pair of small organelles called the centrioles. During animal cell
division, the centrosome divides and the centrioles replicate (make new copies) whereas each
chromosome in its condensed form consists of two chromatids joined at some point along
the length. This point of attachment is called centromere.
