During cell division this shortens to pull the chromatids apart.?
spindle fibers
What are the fibers that shorten and pull the chromatids apart called?
The fibers that shorten and pull the chromatids apart are called microtubules. During cell division, microtubules form the spindle apparatus and attach to the chromosomes to facilitate their separation.
Do the individual chromosomes move apart in mitosis or meiosis?
Yes, in both mitosis and meiosis, the individual chromosomes move apart during cell division. In mitosis, the sister chromatids of each chromosome separate and move to opposite poles of the cell, while in meiosis, homologous chromosomes separate in the first division and sister chromatids separate in the second division.
What gets pulled apart by spindle microtubules?
Chromosomes in the cell are pulled apart by spindle microtubules during cell division to ensure that each new cell receives the correct number of chromosomes.
The framework of microtubules that appears in cell division which eventually moves the chromatids apart is called the?
spindle apparatus
During cell division this shortens to pull the chromatids apart.?

How many chromatids in a cell in which DNA synthesis has occurred prior to cell division?
58 chromatids

How are sister chromatids joined at the centromere during cell division?
During cell division, sister chromatids are joined at the centromere by protein complexes called cohesins. These cohesins hold the sister chromatids together until they are separated during the later stages of cell division.
The framework of microtubules that appears in cell division which eventually moves the chromatids apart is called the?
spindle apparatus
The number of sister chromatids in a human body cell that is entering cell division is?
The number of sister chromatids in a human body cell entering cell division is twice the haploid number, as each chromosome is replicated and consists of two sister chromatids held together by a centromere. This means that there are 46 pairs of sister chromatids in a normal human body cell entering cell division.
How are chromatids separated?
Chromatids are separated during cell division by a structure called the mitotic spindle, which attaches to the centromere of each sister chromatid. The spindle fibers then pull the sister chromatids apart towards opposite poles of the cell, ensuring that each daughter cell receives the correct number of chromosomes.
Chromatids are pulled apart during anaphase?
During anaphase, the sister chromatids (duplicated copies of a chromosome) are pulled apart and move to opposite poles of the cell by the spindle fibers, which are composed of microtubules. This process ensures that each daughter cell receives an identical set of chromosomes during cell division.
What happens to the amount of chromosomes during cell division?
During cell division the chromosomes are copied and they form sister chromatids. Then the mitotic spindle attaches to the sister chromatids and pulls them apart, splitting the nucleus in two. Then the cell goes through cytokenesis and the cell membrane is pinched together in the center, this divides the organelles and the cytoplasm between the two daughter cells.
When do the centromeres split and form the chromatids?
Centromeres split during cell division in the mitotic phase called anaphase. As the sister chromatids are pulled apart towards opposite poles of the cell, the centromeres divide, forming individual chromatids that will become separate chromosomes in the daughter cells.
