Your question: What best describes the events that occur during anaphase quizlet?

aid in sorting and aligning the chromosomes for their movement to opposite ends of the cell. Which of the following phrases best describes the events that occur during anaphase? The spindle fibers shorten and the sister chromatids begin to separate and move to opposite ends of the cell.

What occurs during 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 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).

Which describes the events that occur during anaphase II?

In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.

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 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.

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!

Which of the following 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 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.

What happens during anaphase II of meiosis quizlet?

What happens during anaphase II of meiosis? Sister chromatids separate from each other and migrate to opposite ends of the cell. … Homologous chromosomes separate but sister chromatids remain joined at their centromeres. Meiosis results in genetic variation among its product cells.

What best describes the events that occur during anaphase?

Which of the following phrases best describes the events that occur during anaphase? -The nuclear envelope begins to reform around the newly separated chromosomes and the spindle fiber breaks down. … The spindle fibers shorten and the sister chromatids begin to separate and move to opposite ends of the cell.

What happens during metaphase II?

During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell. … Cytokinesis follows, dividing the cytoplasm of the two cells.

Which of the following events does not occur during prophase quizlet?

Which of the following events does not occur during prophase of mitosis? The mitotic spindle breaks down.

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.

What events occur during Prometaphase?

During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. As a result, the spindle microtubules now have direct access to the genetic material of the cell.
