The paired chromosomes line up along the equator of the cell. This occurs only in metaphase I. In metaphase of mitosis and meiosis II, it is sister chromatids that line up along the equator of the cell.
During which phase do chromosomes line up along the equator?
The spindle fibers will move the chromosomes until they are lined up at the spindle equator. Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.
Where do chromosomes align at the equator?
Answer: (b) metaphase
During metaphase chromosomes are arranged on a plane which is known as an equatorial plate. Metaphase is a stage in which the eukaryotic cell division takes place resulting in the alignment of chromosomes in the middle of the cell.
Why do chromosomes line up at the equator?
The sister chromatids line up at the equator, or center, of the cell. The spindle fibers ensure that sister chromatids will separate and go to different daughter cells when the cell divides. During anaphase, sister chromatids separate and the centromeres divide.
During which phase of mitosis do chromosome line up along the middle of the cell?
Metaphase. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
Do chromosomes align at the equator in meiosis?
Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I. … The chromosomes begin moving toward the equator of the cell. During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells.
What phase is between G1 and G2?
|1.||S phase or synthesis phase is the second sub-phase of interphase.|
|2.||It occurs in between the G1 (Gap 1) phase and G2 (Gap 2) phase.|
|3.||It is the phase of the cell cycle in which DNA replication takes place.|
In what phase do chromosomes not pairs of chromosomes line up in the equator of the cell?
No recombination/crossing over occurs in prophase. In metaphase individual chromosomes (pairs of chromatids) line up along the equator. During anaphase the sister chromatids are separated to opposite poles.
What is a cell equator?
The boundary of a plane through which the division of a cell occurs.
During which phase of mitosis do the chromosomes line up in the center of the cell quizlet?
Metaphase occurs in the middle of mitosis, when the chromosomes line up in the middle of the cell.
