Genetics cell survival

Assembly of vims particles and release from the cell. Vims particles are assembled in infected cells from the new genetic material and viral proteins. Depending on the vims, there are different fates for an infected cell. With many vimses, the infected ceils are killed or lysed at the end of the infection. These vimses are called lytic. Other vimses do not kill the infected cell, but they establish a carrier state in which the cell survives and continually produces vims particles. These vimses are called nonlytic. Some vimses can also establish a case called latency in cells. In these situations, the vims s genetic material remains hidden in the cell, but no vims is produced. At a later time, the latent vims can become reactivated, and the cell will begin to produce infectious particles again. 

Lecithin is the most abundant membrane phospholipid in our cells. A study involving cells with a temperature-sensitive genetic defect in lecithin biosynthesis illustrates how essential it is for cell survival. When grown above a certain temperature, these cells were unable to... 

Important features of cancer cells are enhanced genetic instability, dysregulated and autonomous cell proliferation, increased cell survival, and the ability to survive in a foreign cellular environment which exposes the cell to various stresses. Overall, these properties provide an advantage for the cancer cell.
