During prophase, when cell chromosomes become visible, what are the duplicated strands of DNA called? What is the name for the area in which these duplicated strands are joined?2.What structures are spindle fibers attached to that help pull the paired chromosomes apart? 3.The chromosomes separate and begin to move to opposite sides of the cell.14.hat is the name for the area in which these duplicated strands are joined? 2.What structures are spindle fibers attached to that help pull the paired chromosomes apart? 3.The chromosomes separate and begin to move to opposite sides of the cell. 14.
This is called the interphase. Just before cell division, the chromosomes are duplicated. This is called the S phase. Then mitosis occurs. To facilitate separation of DNA, the chromosomes condense and become visible under light microscopy.Only during the M phase (mitosis) chromosomes are visible.uring interphase, the cell is essentially preparing for mitosis. Thus, the nuclear membrane is still intact. The cell is merely replicating its DNA and chromosomes. During mitosis itself, however, the nuclear membrane breaks down so the chromosomes become visible under a microscope.
