Answer :
The chromosomes, which have already replicated their DNA and are oriented across the middle of the cell, are attached to the microtubules as mitosis continues.
After then, the spindle tubules shorten and migrate in the direction of the cell's poles. The one copy of each chromosome is pulled along by them as they migrate to the opposing poles of the cell.During reproduction, a substance known as DNA (deoxyribonucleic acid) is transmitted from adult organisms to their progeny. The instructions for an organism's growth, survival, and reproduction are contained in this molecule.Your traits, which are qualities or characteristics that you inherit from your parents, are determined by the information carried by your genes (say: trates).
