-Nondisjunction causing an abnormal number of chromosomes.
-Cystic fibrosis due to a mutation in the gene that codes for a specific protein.
-Sickle cell causing abnormally shaped red blood cells.
Answer: A mutation to the p53 gene can cuase cancer since the delay in the cell cycle is disrupted.
A mutation to the p53 gene can cause this type of disease: Cancer since the delay in the cell cycle is disrupted.
A cell cycle is as an ordered sequence of events that takes place within a living cell as it grows and divide into two new daughter cells.
Cancer can be defined as the uncontrolled division of certain body cells, which then invade the surrounding tissues and interfere with the normal functioning of the body.
Some examples of cancer are:
Breast cancer.Prostrate cancer.Carcinoma.A tumor can be defined as an abnormal mass of tissue formed when various body cells grow and divide more than its required or fail to when necessary (required).
Thus, it usually degenerate into cancerous growths (cancer).
