in which cell life cycle phase is a cell highly active and growing?
interphase
the growth process of the cell does not refer to the size of the cell, but the density of the number of cells present in the organism at a given time. cell growth pertains to the increase in the number of cells present in an organism as it grows and develops; as the organism gets larger so too does the number of cells present. cells are the foundation of all organisms, they are the fundamental unit of life. the growth and development of the cell are essential for the maintenance of the host, and survival of the organisms. for this process the cell goes through the steps of the cell cycle and development which involves cell growth, dna replication, cell division, regeneration, and cell death. the cell cycle is divided into four distinct phases: g1, s, g2, and m. the g phase – which is the cell growth phase – makes up approximately 95% of the cycle. the proliferation of cells is instigated by progenitors; the cells then differentiate to become , where cells of the same type aggregate to form tissues, then organs and ultimately systems. the g phases along with the s phase – dna replication, damage and repair – are considered to be the inter-phase portion of the cycle, while the m phase (mitosis and ) is the cell division portion of the cycle. the cell cycle is regulated by a series of signalling factors and complexes such as cyclin-dependent kinase and p53, to name a few. when the cell has completed its growth process, and if it is found to be damaged or altered, it undergoes cell death, either by apoptosis or necrosis, in order to eliminate the threat it can cause to the organism's survival.

section::::cdks and cyclins in the cell cycle.









































most of the known cyclin-cdk complexes regulate the progression through the cell cycle. animal cells contain at least nine cdks, four of which, cdk1, 2, 3, and 4, are directly involved in cell cycle regulation. in mammalian cells, cdk1, with its partners cyclin a2 and b1, alone can drive the cell cycle. another one, cdk7, is involved indirectly as the cdk-activating kinase. cyclin-cdk complexes phosphorylate substrates appropriate for the particular cell cycle phase. cyclin-cdk complexes of earlier cell-cycle phase help activate cyclin-cdk complexes in later phase.
