Alternatively, imagine cyclin levels in daughter cells that never drop; such cells would never stop cycling. WebCheckpoints can delay cell cycle progression or, in response to irreparable DNA damage, induce cell cycle exit or cell death.

WebUncontrolled Cell Divisions Create Tumors including Cancers. Tumors, including cancers, are caused by abnormal cells that multiply continuously. If the abnormal cells continue to divide unstopped, they can damage the tissues around them, spread to other parts of the body ( malignancy ), and even result in death. WebDec 1, 1990 · Molecular genetic analysis of human cancers has shown that tumor cells contain multiple genetic defects including mutations, translocations, and amplifications of oncogenes and are reduced to homozygosity for putative tumor suppressor genes; these phenomena all require cell division for their occurrence and fixation.
