Original Post that I will be editing:
Phases of cell division
[edit]Prophase
[edit]Prophase is the first stage of division. At this point, the nuclear envelope will be broken down. Long strands of chromatin condense to form shorter more visible strands called chromosomes.[1] Chromosomes will also be visible under a microscope and will be connected at the centromere.
Metaphase
[edit]Metaphase is the stage in cell division when the chromosomes line up in the middle of the cell. The chromosomes are till condensing and are currently at one step away from being the most coiled and condensed they will be.[1] At this point, the chromosomes are ready to split into another cell. Spindle fibers start to form in order to begin that process.
MY EDITS:
Phases of Cell Division
[edit]Prophase
[edit]Prophase is the first stage of mitosis. Majority of the time during mitosis is spent during the prophase stage. During this time two pairs of centrioles will move to opposite sides of the cell all while the nuclear envelope is breaking down. As this is happening the chromatids are condensing and form into visible chromosomes, which are connected by a centromere.[1]
Metaphase
[edit]Metaphase is the stage in cell division when the chromosomes line up in the middle of the cell along the metaphase plate. Prometaphase will be the first phase that occurs after prophase, but precedes metaphase. Prometaphase is referring to chromosome movement, while metaphase is referring to the configuration of the chromosomes after they have migrated. The spindle fibers from the centrioles then attach to the centromere, further lining the chromosomes up along the metaphase plate in an arms-out configuration. [2]
