The eukaryotic cell cycle is very complex and is one of the most studied topics, since its misregulation leads to cancers. It is possibly a good example of a mathematical model as it deals with simple calculus but gives valid results. Two research groups [1] [2] have produced several models of the cell cycle simulating several organisms. They ...
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
A screenshot from the video, depicting a motor protein moving a vesicle by crawling along a microtubule. The Inner Life of the Cell is an 8.5-minute 3D computer graphics animation illustrating the molecular mechanisms that occur when a white blood cell in the blood vessels of the human body is activated by inflammation ( Leukocyte extravasation ).
Flipped classroom teaching at Clintondale High School in Michigan, United States. A flipped classroom is an instructional strategy and a type of blended learning.It aims to increase student engagement and learning by having pupils complete readings at home, and work on live problem-solving during class time.

The citric acid cycle is a series of enzymatic reactions carried out inside the inner membranes of the cell's mitochondria. The process begins when the two-carbon acetyl CoA enters the cycle and joins the four-carbon oxaloacetate to produce the six-carbon citrate.

If is cellular with cell-datum (,,,) and is an ideal (a downward closed subset) of the poset then ():= (where the sum runs over and , ()) is a two-sided, -invariant ideal of and the quotient / is cellular with cell datum (,,,) (where i denotes the induced involution and M, C denote the restricted mappings).
The state of each cell in a totalistic cellular automaton is represented by a number (usually an integer value drawn from a finite set), and the value of a cell at time t depends only on the sum of the values of the cells in its neighborhood (possibly including the cell itself) at time t − 1.
