Homework Answers
- during metaphase, chromosomes line up along the equator of the cell.
- The two sister chromatuds are held together with a centromere
- cytokinesis refers to the division of the cytoplasm into two daughter cells.
- genetic information in cells is contained in structure called chromosomes
- during anaphase, part of the mitotic spindle can be seen attached to the centromere of each sister chromatid
- the constricted appearance of cell membrane prior to the formation of two daughter cells in animals is called cleavage furrow

Which of the following mitosis phases is correctly matched with its description? Group of answer choices prophase- nuclear envelope disintegrates and chromatin condenses into chromosomes metaphase- chromosomes line up at the equator anaphase- chromosomes separate into sister chromatids and are pulled to opposite sides of the cell telophase- chromosomes "relax" and decondense back into chromatin; the nuclear envelopes reform to create two nuclei; cytokinesis splits the cell in half to form two cells all of the above are correct 2....
