Prometaphase

Third phase in mitosis, sometimes considered part of the prophase. The nuclear membrane dissolves, marking the beginning of prometaphase. Proteins attach to the centromeres creating the kinetochores. Microtubules attach at the kinetochores and the chromosomes begin moving.

Animal cell nucleus shape changes

... I know. During mitosis the nucleus is disintegrated for a period of time, in a controlled manner. 2) During cell division there is a phase (from prometaphase onwards) where one could perhaps describe the nucleus to be amorphous, as it has no defined shape. That statement would thus correctly ...

Compare and contrast the processes of Mitosis and Meiosis

... occurs to replace damaged cells, to grow and to repair our bodies. This is just about all I know, I know that Mitosis occurs in stages (Prophase, prometaphase, metaphase anaphase and telophase). Please elaborate on this, anything that you deem important will be imperative for me to understand ...

Mitosis

I am confused about anaphase, prometaphase and metaphase. I think anaphase is paired homologous chromosomes separate and begin to move to opposite poles of the cell. The sister chromatids remain together, metaphase is the spindle fully develops ...

Cell cycle

... stained; at 9.0 hr 2 of 16 mitotic cells were stained; at 9.5 hr 16 of 16 mitotic cells were stained. (mitotic cells are all cells in prophase, prometaphase, metaphase and anaphase) iii) The first BrdU positive cells in late telophase were seen at 10.5 hr after labeling. 2A. Determine the length ...

Re: Unusual cell division- Identifying mutant protein and genes

... think and we'll proceed. Telophase Main article: Telophase Telophase (from the Greek τελος meaning "end") is a reversal of prophase and prometaphase events. It "cleans up" the after effects of mitosis. At telophase, the nonkinetochore microtubules continue to lengthen, elongating ...
