Mitosis is conventionally divided into five stages known as prophase, prometaphase, metaphase, anaphase, and telophase. While mitosis is taking place, there is no cell growth and all of the ...

This mid-prophase PtK 1 cell was induced to return to antephase simply by cooling it to 20 °C (a–c), and was then induced to re-enter mitosis by warming to 37 °C (c–e). Times in h:min are ...

Interphase The cell spends most of its life in this phase. The DNA in chromosomes copies itself ready for mitosis. Prophase The DNA in chromosomes and their copies condenses to become more visible.

As in prophase I, the chromosomes condense, spindles form, the centrioles begin to separate, and the nuclear membrane fragments and disperses. Unlike prophase I, the chromosomes do not attach to ...

This solution is called meiosis. Mitosis describes the process by which the nucleus of a cell divides to create two new nuclei, each containing an identical copy of DNA. (Cytokinesis describes the ...

For decades, scientists observed clathrin-mediated endocytosis (CME)—the process of forming vesicles to pull protein cargo into a cell—ceasing during mitosis in mammalian cells. But they didn’t know ...
