What Has to Happen Before Mitosis Can Occur?

Walther Flemming's cartoon of chromosomes.

Most cells abound, perform the activities needed to survive, and divide to create new cells. These basic processes, known collectively equally the jail cell bike, are repeated throughout the life of a cell. Of the diverse parts of the cell cycle, the partition portion is particularly important, because this is the point at which a cell passes its genetic information to its offspring cells. In many situations, division besides ensures that new cells are available to replace the older cells within an organism whenever those cells dice.

Prokaryotic cells, which include bacteria, undergo a type of jail cell partitioning known every bit binary fission. This process involves replication of the prison cell'south chromosomes, segregation of the copied DNA, and splitting of the parent cell'southward cytoplasm. The outcome of binary fission is two new cells that are identical to the original prison cell.

In contrast to prokaryotic cells, eukaryotic cells may carve up via either mitosis or meiosis. Of these 2 processes, mitosis is more common. In fact, whereas only sexually reproducing eukaryotes can engage in meiosis, all eukaryotes — regardless of size or number of cells — can engage in mitosis. Just how does this process proceed, and what sorts of cells does information technology produce?
