In 1928, Arizona Cleaver became the third wife of James Samuel Stemons, a writer and union organizer. [15] James Stemons died in 1959. [16] Arizona Cleaver Stemons died in March 1980, aged 81 years, in Philadelphia. [3] [17] The Philadelphia graduate chapter of Zeta took ownership of her home after her death, and continues to maintain the property.
APC activity also causes the destruction of S and M cyclins and thus the inactivation of Cdks, which promotes the completion of mitosis and cytokinesis. APC activity is maintained in G1 until G1/S–Cdk activity rises again and commits the cell to the next cycle. This scheme serves only as a general guide and does not apply to all cell types. [1]
as external source i used another structure found on the book "molecular cell biology" from james darnell, harvey lodish and david baltimore. i tried to convine all in a complete yet simple diagram. i finish it on the 03-feb-05 —LadyofHats 01:12, 3 Feb 2005 (UTC)" Between the changes made are: removed the leucoplast, under request.
Multiple macromolecules form a cell, like a club cell. A group of cells functioning together as a tissue, for example, Epithelial tissue. Different tissues make up an organ, like a lung. Organs work together to form an organ system, such as the Respiratory System. All of the organ systems make a living organism, like a lion.

The cell cycle is a series of complex, ordered, sequential events that control how a single cell divides into two cells, and involves several different phases. The phases include the G1 and G2 phases, DNA replication or S phase, and the actual process of cell division, mitosis or M phase. [ 1 ]
