SOLUTION Biology cell cycle Biology Diagrams The graphic below shows a visual representation of the cell cycle. The small section labeled "M" represents mitosis, while interphase is shown subdivided into its major components: the G 1, S, and G 2 phases. This cell cycle is used by all eukaryotic cells to produce new cells.

The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle. DNA duplication occurs during S phase (S for synthesis), which requires 10-12 hours and occupies about half of the cell-cycle time in Eucaryotic cells have evolved a complex network of regulatory proteins, known as the cell-cycle control system, that governs progression through the cell cycle.The core of this system is an ordered series of biochemical switches that control the main events of the cycle, including DNA replication and the segregation of the replicated chromosomes. In most cells, additional layers of regulation

Genes and cDNA clones have been identified in animal cells that are cell cycle-regulated, i.e. they are preferentially expressed in a phase of the cell cycle. Molecular biology of the cell cycle Int J Radiat Biol Relat Stud Phys Chem Med. 1986 Feb;49(2):219-26. doi: 10.1080/09553008514552511. Author R Baserga. PMID: 3510991 DOI: 10.1080

Eventually, the pace of the cell cycle speeds up as the effectiveness of the control and repair mechanisms decreases. Uncontrolled growth of the mutated cells outpaces the growth of normal cells in the area, and a tumor can result. 13.4.1 Proto-oncogenes. The genes that code for the positive cell cycle regulators are called proto-oncogenes. Analysis of Cell cycle. Cell cycle analysis is a method in cell biology that employs flow cytometry to distinguish cells in different phases of the cell cycle. Before analysis, the cells are permeabilised and treated with a fluorescent dye that stains DNA quantitatively, usually propidium iodide (PI).

The cell cycle is the sequence of events occurring in an ordered fashion which results in cell growth and cell division. G0, G1, S, G2, M.
