What major events occur during anaphase of mitosis? The sister chromatids of replicated chromosomes separate, and the spindle poles are pushed farther apart. Identify the events in the cell cycle that must be completed successfully for daughter cells to share an identical complement of chromosomes.
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 event or events occurs during anaphase?
The major events that occur during anaphase of mitosis are the separation of sister chromatids to opposite sides of the cell.
Which of the following events occurs during anaphase I?
Figure 3: During anaphase I, the homologous chromosomes are pulled toward opposite poles of the cell. During anaphase I, the microtubules disassemble and contract; this, in turn, separates the homologous chromosomes such that the two chromosomes in each pair are pulled toward opposite ends of the cell (Figure 3).
What events occur during prophase quizlet?
Which events occur during prophase? The nuclear envelope breaks down. Chromosomes condense and are attached to spindle fibers. You just studied 30 terms!
What occurs in anaphase quizlet?
What happens during Anaphase? The spindle fibers SPLIT APART the sister chromatids and move them to opposite ends of the cell, equally dividing the genetic material. … A new nuclear membrane forms around each new set of chromosomes, each with the same number of chromosomes as the original cell.
Which of the following events occur during anaphase II?
During anaphase II and mitotic anaphase, the kinetochores divide and sister chromatids, now referred to as chromosomes, are pulled to opposite poles. The two daughter cells of mitosis, however, are identical, unlike the daughter cells produced by meiosis.
What key event 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.
Which of the following events occurs during anaphase 1 of meiosis?
Question: Which of the following events occurs during anaphase 1 of meiosis? The nuclear envelope breaks down and the spindle fibers form. The chromosomes line up in the middle of the cell. The cell divides into two daughter cells via cytokinesis.
Which of the following occurs during S phase?
Which of the following is a function of the S phase in the cell cycle? The synthesis of sister chromatids, DNA replication occurs during S phase and results in two sister chromatids for each original chromosome. … Chromosomes must undergo replication before mitosis can occur; this copying occurs during the S phase.
Which event occurs during interphase quizlet?
During this phase of interphase, DNA replication takes place making two identical copies of the genome of the cell. When the chromosomes become visible they will appear as double chromosomes as they have two copies of DNA instead of one. During this phase of interphase, the cell grows and prepares for mitosis.
