WebNov 5, 2024 · Spindle fibers pull the chromosomes towards the center of the cell; they align the chromosomes at the equator of the cell, and the equator is an imaginary plane that divides the cell into two halves. Hence, the following events occur during metaphase: chromosomes line up at the equator, which is in Option D. Learn more about the … WebThe aim of the mitotic process is to segregate the genetic material packed into duplicated chromosomes equally between two daughter cells. To accomplish this, cells form a highly dynamic yet robust structure called the mitotic spindle [1,2,3].In the majority of higher eukaryotes, chromosomes attach to spindle microtubules (MTs) by kinetochores, large …
WebAfter anaphase, the phragmoplast emerges from the remnant spindle MTs in between the daughter nuclei. MT plus ends overlap the equator of phragmoplast at the site where the cell plate will form. The formation of … Attachment of microtubules to chromosomes is mediated by kinetochores, which actively monitor spindle formation and prevent premature anaphase onset. Microtubule polymerization and depolymerization dynamic drive chromosome congression. Depolymerization of microtubules generates tension at kinetochores; bipolar attachment of sister kinetochores to microtubules eman…
WebJun 8, 2024 · 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 ... Webspindle cell. A generic term for an elonged and/or fusiform cell, regardless of origin. Lineage.
