Answer:
6
Step-by-step explanation:
In the cell that is in the process of dividing, each condensed chromosome appears as a pair of rods joined at a certain point, the centromere. These two chromosomal “halves”, called sister chromatids are identical and arise from the duplication of the original chromosomal filament, which occurs in the interphase, just before cell division begins.
In summary, we can say that a centromere is the structure that holds a pair of chromosomes together, so if six centromere are observed in a prophase cell, it means that there are six pairs of chromosomes in that cell.
