Your question: What happens when pairs of sister chromatids align at the center of the cell?

During metaphase, the microtubules pull the sister chromatids back and forth until they align in a plane, called the equatorial plane, along the center of the cell. … Anaphase ensures that each daughter cell receives an identical set of chromosomes.

What is at the center connecting the sister chromatids?

Because each duplicated chromosome consists of two identical sister chromatids joined at a point called the centromere, these structures now appear as X-shaped bodies when viewed under a microscope.

Why does chromosomes move and align themselves at the center of the cell?

1. Microtubules are responsbile for moving Chromosomes to the metaphase plate. During Prometaphase, microtubules grow into a region around the Chromosomes until they find a Kinetochore. A Microtubule from each spindle pole connects to the kinetochore of each Chromosome.

What is the fate of sister chromatids during mitosis?

By the end of mitosis, a series of reactions separate the two sister chromatids, moving them towards opposite ends of the dividing cell, and a new cell membrane forms between them, creating two daughter cells. Both the cells are genetically identical to the parent cell.

What can happen if cells do not duplicate correctly?

Answer: If the cell has not properly copied its chromosomes, an enzyme called cyclin dependent kinase, or CDK, will not activate the cyclin, and the cell cycle will not proceed to the next phase. The cell will undergo cell death.

What phase are daughter cells in as a result of mitosis?

Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.
