"The Cell Cycle and Cancer"

Download file to see previous pages G1 phase, where synthesis of “RNA, protein, and organelle” takes place is the second phase that precedes the S phase (Dudek, 2006, p. 123). At the S phase, DNA molecules synthesizes before “ATP synthesis” at the G2 phase (Dudek, 2006, p. 123). The last phase of the cell cycle is the M phase. It is the stage at which cells divide and consists of a number of stages, “prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis” (Dudek, 2006, p. 123). A change in regulation in the cell cycle, leading to cancer, is therefore most likely to occur at the M phase of the cell cycle. This is because cancer cells results from uncontrollable cell division, yet cell division at the M phase (Hacker, Messer and Benchmann, 2009).
There exist a number of differences between normal cell cycle and cancer cell cycle. Normal cell cycle is for example regulated by cell environmental factors while cancer cell cycle is independent. Unlike cancer cell cycle, normal cell cycle is limited to available space. The normal cells also die, unlike cancer cells (Annenberg Foundation, n.d.).

What Causes Cancer Mutations
What Causes Cancer Mutations? Cancer is known as malignant neoplasm, the hallmark characteristic involves uncontrolled proliferation of cells. Under normal conditions cells grow, divide and die, but in a genetic defect called mutation occur in cancer cells leading to the formation of an abnormal DNA.

Reprogramming of Cancer Cells
Mutations in genes resulting in Cancer: Basically cancer arises due to mutations in different genes which result in the uncontrolled division of the cells which allow these abnormal cells to invade the normal cells of the body. Genes are basically a coding system inside the cell which directs the cell to perform its functions through the synthesis of different proteins which are encoded by different genes.

B-cell Cancer and Different Stages of B-lymphocyte Development
These proteins in turn control the behaviour of the cell. Just like any other cell, the human body makes millions of various types of B cells everyday and each type has a unique receptor protein on its membrane that will bind to one particular antigen. B cells are white blood cells (lymphocytes) that play a vital role in the production of antibodies and the accessory processes that accompany it (humeral immune system).

Impact of DNA damage induced by anticancer drugs on both S phase and mitosis phase of the cell cycle
Many genetic changes happen when a normal cell is converted to a cancer cell (Hartwell & Kastan 1994). In a carcinoma cell the normal order and the functions of a cell are impaired and the usual limits of cell division are ignored. This condition may arise as a result of a mutation / change of the genetic sequence or due to DNA damage and it is important to note that the ‘growth fraction’ (ratio of proliferating cells to cells in resting stage) is remarkably high in carcinoma cells than in normal cells (Eidukevicius et al.

P53 mutations and Cancer
If we have to differentiate between the normal cells and cancer cells, it can be noted that the cancer cell seems to have lost a number of vital control systems. Here comes the concept of genes which is the most important ingredient in the cell responsible for multiplication.

Cancer at the molecular level
As genes are the basic control machine of the cell, alteration of any kind may bring devastating consequences, or malignancy. Moreover, in normal cells damage of any kind is taken care by the repair system but in cancer cells, the repair function is altered, hence damaged DNA is not repaired, occurs, cells divide continuously without displaying senescence, generating a series of abnormal cells (Alberts, 2007).
