During which phase of meiosis do the sister chromatids line up across from each other in the center of the cell metaphase 1 or 2?
During prophase I, homologous chromosomes form tetrads along the center of the cell. Full chromosomes are pulled to each pole during anaphase I, resulting in two haploid cells at the end of meiosis I. During prophase II, sister chromatids align at the center of the cell in singular chromosome structures.
In what phase of meiosis do the sister chromatids line up at the equator?
During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane. There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.
During which phase of meiosis do the sister chromatids line up across from each other in the center of the cell quizlet?
During metaphase, spindle fibers attach to the centromere of each pair of sister chromatids. The sister chromatids line up at the equator, or center, of the cell.
What is the first stage of meiosis during which a cell is considered haploid quizlet?
During anaphase I the rplicated homologous chromosomes are separated (the tetrad is split) and pulled to opposite sides of the cell. The fourth of meiosis I. the number of chromosoms is now reduced by half. After this phase the cell is considered to be haploid.
In which stage of meiosis would you find Tetrads of chromosomes aligned at the center of the cell followed thereafter by independent assortment?
In metaphase I, the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. In anaphase I, centromeres break down and homologous chromosomes separate. In telophase I, chromosomes move to opposite poles; during cytokinesis the cell separates into two haploid cells.
What lines up at the equator of the cell during meiosis II?
During metaphase II, sister chromatids are condensed and aligned at the equator of the cell. During anaphase II sister chromatids are pulled apart by the kinetochore microtubules and move toward opposite poles.
