In which stage of mitosis do chromosomes move to the opposite ends of the cells along the spindle fibers?
During anaphase, the sister chromatids are separated and pulled to opposite ends of the cell. During telophase, the nuclear envelope begins to re-form around the divided chromatids.
What happens in meiosis I?
In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.
What happens in metaphase I?
At metaphase I, the homologous chromosomes move to the center of the cell and orient themselves along an equatorial plane, forming the so-called metaphase plate.
What happens during telophase 1 in meiosis?
During telophase I, the chromosomes are enclosed in nuclei. The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
Which phase of mitosis is characterized by each pair of sister chromatids moving to opposite sides of the cell?
Anaphase, is the stage of mitosis or meiosis when chromosomes are split and the sister chromatids move to opposite poles of the cell.
What are the 4 stages of mitosis and what happens in each?
There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister …
