Which of the following events occurs during metaphase of mitosis quizlet
Which of the following events occurs during metaphase of mitosis? The chromosomes align along the metaphase plate of the cell.
Which of the following occurs during metaphase two
The correct answer is (b) Chromosomes migrate to the middle of the cell. Just as in metaphase of mitosis, metaphase II of meiosis occurs when
What occurs during metaphase II of meiosis
Metaphase II: The paired chromosomes line up. Anaphase II: The chromatids split at the centromere and migrate along the spindle fibers to opposite poles. Telophase II: The cells pinch in the center and divide again. The final outcome is four cells, each with half of the genetic material found in the original.
Which of the following happens during metaphase check all that apply
The correct answer is (b) Chromosomes migrate to the middle of the cell. Metaphase I is the second stage of the first division of meiosis.
Which of the following events occurs during prophase
During prophase, the chromosomes condense and centrosomes move to opposite sides of the nucleus, initiating formation of the mitotic spindle.
What events occur in meiosis
Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice — once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II.
What is the definition of metaphase 1
Definition. The first metaphase of meisosis I encompasses the alignment of paired chromosomes along the center (metaphase plate) of a cell, ensuring that two complete copies of chromosomes are present in the resulting two daughter cells of meiosis I.
Which of the following occurs during telophase
What Happens during Telophase? During telophase, the chromosomes arrive at the cell poles, the mitotic spindle disassembles, and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes.
Why do chromosomes line up during metaphase
Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
Which of the following occurs during anaphase
During anaphase, each of the cell's 46 chromosomes is split into singular chromatids, and each chromatid is considered a separate chromosome structure for a total of 92 chromosomes. Once the cell completes division, these chromatids are sequestered into separate nuclei and the cell returns to its normal diploid state.
What are the 4 stages of the cell cycle
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).
In what order do events occur during mitosis quizlet
What is the correct order of mitosis? prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis.
What is the major event that occurs during mitosis
These basic events of mitosis include chromosome condensation, formation of the mitotic spindle, and attachment of chromosomes to the spindle microtubules. Sister chromatids then separate from each other and move to opposite poles of the spindle, followed by the formation of daughter nuclei.
What major events occur during prophase of mitosis
What Happens during Prophase? Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.
Which sequence of stages in mitosis is correct
The correct answer is (b) prophase, prometaphase, metaphase, anaphase, telophase. The major events that occur during each stage are summarized
What are the major events of telophase
During telophase, the chromosomes begin to decondense, the spindle breaks down, and the nuclear membranes and nucleoli re-form. The cytoplasm of the mother cell divides to form two daughter cells, each containing the same number and kind of chromosomes as the mother cell.
Which of the following do not occur during telophase
Which of the following does not occur during telophase: The nuclear membrane disappears.
Which of the following does not occur in telophase
Which does NOT occur in telophase? The centromeres split apart, moving to opposite ends of the cell. Generally, complex organisms do require more genes to control their synthesis and organization than do primitive organisms.
