The furrow deepens as the actin ring contracts, and eventually the membrane and cell are cleaved in two (Figure 6.5). Select one: a. prophase II b. metaphase II c. anaphase I d. metaphase I e. prophase I. Blood Flow and Blood Pressure Regulation, 22.2. Chromosomes line up in the center of the cell. As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. This allows for the formation of gametes with different sets of homologues. The nucleus re-forms and the cell divides. The first portion of the mitotic phase, mitosis, is composed of five stages, which accomplish nuclear division. Recent research suggests, however, that this is an oversimplification and that chromosomes may actually occupy specific territories within the nucleus (Cremer & Cremer, 2001). The nucleus re-forms and the cell divides. However, during the G1 stage, the cell is quite active at the biochemical level. (Interphase, Prophase, Metaphase, Anaphase, Telophase). Note the other types of microtubules involved in anchoring the spindle pole and pulling apart the sister chromatids. Mitosis consists of five stages: prophase, prometaphase, metaphase, anaphase, and telophase. a. metaphase b. prophase c. anaphase d. interphase e. telophase. Metaphase II: Chromosomes line up at the metaphase plate. The chromosomes begin to decondense and return to their stringy form. The drawstring is a band of filaments made of a protein called actin, and the pinch crease is known as the. Spindle fibers not connected to chromatids lengthen and elongate the cell. During which stage of a cell's cycle do the replicated chromosomes line up on the equator of the cell? So, during. A) interphase B) prophase C) metaphase D) anaphase E) telophase. a. metaphase b. prophase c. anaphase d. interphase e. telophase. Like cohesin, condensin is an elongated complex of several proteins that binds and encircles DNA. metaphase I d). The two centrosomes will give rise to the mitotic spindle, the apparatus that orchestrates the movement of chromosomes during mitosis. The kinetochore becomes attached to metaphase plate. a. Telophase 2 b. Interphase 1 c. Prophase 2 d. Metaphase 1, Which of the following phases occurs during mitosis? At what stage do the chromosomes double during mitosis?
