Which of the following is the best description of the events of anaphase 1?
Which of the following is the best description of the events of anaphase I? Homologous chromosomes randomly separate and migrate to opposite poles. Which of the following occurs during prophase?
What happens in the anaphase 1?
In anaphase I, the homologues are pulled apart and move apart to opposite ends of the cell. The sister chromatids of each chromosome, however, remain attached to one another and don’t come apart. Finally, in telophase I, the chromosomes arrive at opposite poles of the cell.
Which of the following best describes the events of anaphase I of meiosis?
Which of the following best describes the events of anaphase I of meiosis? The two pairs of sister chromatids migrate to the same pole. Each homologous pair of sister chromatids migrates to opposite poles.
Which of the following occurs during anaphase I?
Homologs separate and migrate toward opposite poles. Sister chromatids separate and migrate toward opposite poles. Nuclei re-form. Chromosomes line up in one plane.
Which is the best description of events that take place during anaphase ll?
Homologous chromosomes travel to opposite sides of the cell. Sister chromatids are pulled apart at the centromere. Which is the best description of the events that take place during anaphase II? The replicated chromosomes become visible.
Which is the best description of the events of anaphase 2?
Anaphase II is the stage when sister chromatids of every chromosome separate and begin to move towards the opposite ends of the cell. The separation and the movement is due to the shortening of the kinetochore microtubules. Anaphase II precedes telophase II. Meiotic anaphase II is similar to the anaphase in mitosis.
What is anaphase2?
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. In the case of males, each cell becomes a sperm.
What is Interkinesis in meiosis?
Interkinesis or interphase II is a period of rest that cells of some species enter during meiosis between meiosis I and meiosis II. No DNA replication occurs during interkinesis; however, replication does occur during the interphase I stage of meiosis (See meiosis I).
What is anaphase in cell cycle?
Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. … The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
Which of the following best describes what occurs during metaphase?
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. … As metaphase continues, the cells partition into the two daughter cells.
Which statement best describes the events taking place during the anaphase stage of mitosis?
In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.
Which of the following best describes anaphase II of meiosis quizlet?
Which of the following best describes anaphase II of meiosis? Sister chromatids are pulled apart.
Which of the following events occur during anaphase I quizlet?
During anaphase I, the homologous chromosomes (paired bivalents) separate from each other. Homologues reach their respective poles during telophase I, the nuclear membrane re-forms to produce two separate nuclei.
Which of the following events occurs in prophase 1?
The main events of prophase are: the condensation of chromosomes, the movement of the centrosomes, the formation of the mitotic spindle, and the beginning of nucleoli break down.
Which of the following does occur during anaphase 1 of meiosis quizlet?
Which of the following DOES occur during anaphase I of meiosis? The chromosomes move toward the poles. A potential disadvantage of asexual reproduction is that: it produces genetically uniform populations.
