Most cells grow, perform the activities needed to survive, and divide to create new cells. These basic processes, known collectively as the cell cycle, are repeated throughout the life of a cell. Of ...

A putative ubiquitin conjugating enzyme known as UBE2Q2 was previously identified in a microarray screen for mitotic regulatory proteins. UBE2Q2 is very similar to another human protein, UBE2Q1 and ...

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 the ...

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.

Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell ...
