Merriam-Webster: The most frequently repeated remark about it is that âthere is no such word.â There is such a word, however. It is still used primarily in speech, although it can be found from time to time in edited prose. Its reputation has not risen over the years, and it is still a long way from general acceptance.
What cellular component helps pull the chromosomes apart in mitosis and meiosis? The cellular component that helps pull apart the chromosome in mitosis and meiosis are the spindle fibers. These spindle fibers are made of micro-tubules.
During prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes (sister chromatids). During metaphase, the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers. During anaphase, sister chromatids are separated at the centromere and are pulled towards opposite poles of the cell by the mitotic spindle. During telophase, chromosomes arrive at opposite poles and unwind into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears.
