Document Summary
Carcinogenesis the onset of cancer formation. Monolayer formed at aquous interfaces by amphipathic compounds. Contact inhibition growth mechanism which functions to keep cells growing into a monolayer. If a cell has plenty of free space, it replicates rapidly and moves freely. This process occurs until there is no more room to replicate. Apoptosis process of programmed cell death. Aneuploidy presence of an abnormal # of chromosomes (45 or 46) Metastasis spread of a cancer/disease of one organ to another not directly connected to it. Initiation initiators are altered via drug-metabolizing enzymes in the body and are then able to cause changes in dna mutations. Promotion promote proliferation of the cell, giving rise a large number of daughter cells containing the mutation created by the initiator. Oncogene a gene that in certain circumstances can transform a cell into a tumor cell. 16. 1 the properties of a cancer cell.
