WebOct 29, 2024 · Without the use of enzymes, the spindle fibers are more precisely distinguishable, whereas with the use of enzymes, the fibers are overlapped between each other. Previous studies from our lab have demonstrated that localization SYN1 cohesin protein localizes to arms of meiotic chromosomes from approximately meiotic interphase … WebDuring 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.
