Answer:
Six centromeres are observed in a prophase cell from an insect, there are 20 pairs of chromosomes present.
Explanation:
Centromeres is defined as the part of the DNA which are held responsible for the directional changing of chromosomes.
And these chromosome gets divided into 2 daughter cells while undergoing the process of mitosis and meiosis.
Chromosome is basically defined as a thin structure as of a threadlike which is made out of nuclei acid and protein which is located at the nucleus of various living cells
Answer:
6
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.
