The two parts of the cellarrow_forwardWhat is the function of the kinetochore during mitosis?a. It promotes the attachment of monads to each other toform a dyad.b. It is a location where a kinetochore microtubule can attachto a chromosome.c. It promotes the condensation of chromosomes duringprophase.d. Both a and b are correct.arrow_forwardWhich of the following statements is FALSE? A. Centrosomes are anchor points for microtubules and are essential to form the mitotic spindle. B. In the eukaryotic cell cycle the cell spends much more time in the interphase than in the mitotic phase. C. In telophase two nuclear envelopes are fully formed and the cell splits in two via cytokinesis. D. The contraction of the kinetochore microtubules leads to the separation of the sister chromatids during anaphase. E. In the prophase chromatin condenses into X-shaped chromosomes.arrow_forward

The chromosomes would not condense B. The nuclear envelope would not dissolve C. The chromosomes would not line up for metaphase D. The chromosomes would line up for metaphase but would not pull apart in anaphase.arrow_forwardThe amount of DNA per cell of a particular species is measured in cells found at various stages of meiosis and the following amounts are obtained: 3.7 pg , 7.3 pg , and 14.6 pg.
