![]() ![]() The continuity of life is based on heritable information in the form of DNADNA. At anaphase, mitotic spindles pull the chromatids toward the poles of the cell, therefore forming two identical chromosomal sets at each pole. During mitosis, each chromatid of a duplicated chromosome becomes attached to the microtubule of one of the mitotic spindles. Label the stages, the nuclear envelope and any microtubules attached to the chromosome(s). anaphase the chromatids of each chromosome have separated, and the daughter chromosomes are moving to the ends of the cell as their kinetochore microtubules shorten. prophase the chromosomes are condensing and the nucleolus is beginning to disappear. ![]() ![]() Later the nuclear envelope will fragment. prometaphase discrete chromosomes are now visible each consists of two aligned, identical sister chromatids. Cytokinesis has started: The cell plate, which will divide the cytoplasm in two, is growing toward the perimeter of the parent cell. interphase Identify a cell in each of the following stages: metaphase the spindle is complete, and the chromosomes, attached to microtubules at their kinetochores, are all at the plate. 32 Beginning with a fertilized egg (zygote), how many cells will be present in the embryo following five rounds of cell division? G1 Cell A has half as much DNA as cells B, C, and D in a mitotically active tissue. ![]()
