The cell cycle, or cell-division cycle, is the sequence of events that take place in a cell and lead to its division into two daughter cells. These events include the growth of the cell, duplication o
Onion (Allium) cells in different phases of the cell cycle. Growth of the organism is carefully controlled by regulating the cell cycle.
Cytokinesis in animal cells and plant cells
Overview of the cell cycle checkpoints, visual reference of what it does and where it happens.
Overviews of the G1/S transition control networks in plants, animals, and yeast. All three show striking network topology similarities, even though individual proteins in the network have very little sequence similarity.
Mitosis is a part of the cell cycle in eukaryotic cells in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis is an equational division which gives rise to geneti

…nucleus) including animal, plant, fungal, and protist cells, the cell cycle is divided into two main stages: interphase, and the M phase that includes mitosis and cytokinesis. During interphase, the cell grows, accumulating nutrients needed for mitosis, and replicates its DNA and some of its organelles. Its…
