What happens in the second stage of mitosis?
second main stage of the cell cycle during which the cell's replicated DNA divides and two genetically identical diploid daughter cells are produced Anaphase third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell
What happens in anaphase 3 of mitosis?
Anaphase third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell Centromere cell structure that joins two sister chromatids
Which phase of the cell cycle holds sister chromatids together?
holds sister chromatids together. Metaphase Prophase Anaphase Telophase Interphase--longest part of cell cycle, when cells grow, develop and duplicate DNA and organelles to prepare for mitosis. Cell cycle consists of these three phases
Which structure is formed during the first stage of mitosis?
first stage of mitosis, during which the cell's chromatin condenses into chromosomes Sister Chromatid structure that contains identical DNA copies and is formed during DNA replication
During which stage of mitosis do the sister chromatids get pulled to opposite ends of the cell anaphase Interphase metaphase telophase?
anaphaseMetaphase leads to anaphase, during which each chromosome's sister chromatids separate and move to opposite poles of the cell.
During which phase of mitosis are sister chromatids pulled to opposite ends of the cell quizlet?
As Spindle Fibers ? during Anaphase they pull the sister chromatids to opposite ends of the cell.
Which phase of the cell cycle is when the sister chromatids of the chromosomes are pulled apart and initially separated?
anaphaseDuring anaphase, the sister chromatids at the equatorial plane are split apart at the centromere. Each chromatid, now called a chromosome, is pulled rapidly toward the centrosome to which its microtubule was attached.
In what phase of meiosis are sister chromatids separated and pulled to opposite ends of the cell anaphase I anaphase II metaphase II metaphase I?
In metaphase II, the chromosomes line up individually along the metaphase plate. 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.
During which phase of mitosis are sister chromatids pulled apart and begin to move to opposite sides of the cell quizlet?
Before mitosis, the centrosomes are close together, but they begin to move to opposite sides of the cell during prophase.
During which phase of meiosis are chromatids pulled to opposite poles of the cell quizlet?
In anaphase, the sister chromatids are pulled apart to opposite ends of the cell.
What happens in G1 phase?
Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.
What are the 4 phases of mitosis and what happens in each?
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 chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope ...
In which phase of mitosis do the sister chromatids become daughter chromosomes?
Sister chromatids of a chromosome separate and start to travel towards opposite poles during anaphase of mitosis. Sister chromatids become individual chromosome as soon as they separate. Hence answer will be ANAPHASE .
In which stage of meiosis are sister chromatids separated and pulled to the opposite pole?
Anaphase IIAnaphase II: During anaphase II, the centromere splits, freeing the sister chromatids from each other. At this point, spindle fibers begin to shorten, pulling the newly-separated sister chromatids towards opposite ends of the cell.
Do sister chromatids separate during anaphase 1 or anaphase 2?
In anaphase I, the homologous chromosomes are separated. In prometaphase II, microtubules attach to the kinetochores of sister chromatids, and the sister chromatids are arranged at the midpoint of the cells in metaphase II. In anaphase II, the sister chromatids are separated.
At which stage of meiosis are sister chromatids separated from each other prophase I prophase II anaphase I anaphase II?
Sister chromatids are not separated until meiosis II. The fused kinetochore formed during meiosis I ensures that each spindle microtubule that binds to the tetrad will attach to both sister chromatids.
