4. INTRODUCTION Given the changes in the internal or external environment the body has the ability to respond to changes. Without these skills, the cells wouldn't have the capacity to live and continue reproducing.

6. SMALLER SIBLING PROTEIN CALLS THE SHOTS IN CELL DIVISION SCIENCEDAILY (JAN. 3, 2012) Taken from: http://en.wikipedia.org/wiki/DNA_repair The protein Chk1 works as a checkpoint in cell development, this protein avoids cell division until their DNA has been fully replicated or repaired.

10. INFLAMMATORY MEDIATOR PROMOTES COLORECTAL CANCER BY STIFLING PROTECTIVE GENES SCIENCEDAILY (JAN. 22, 2012) The development of colorectal cancer by shutting down genes that suppress tumors and repair damaged DNA it's increase by the function of a chemical that promotes inflammation, called prostaglandin E2 (PGE2).

12. INFLAMMATORY MEDIATOR PROMOTES COLORECTAL CANCER BY STIFLING PROTECTIVE GENES SCIENCEDAILY (JAN. 22, 2012) Taken from: http://www.astronoo.com/articles/regeneracionDeLosTejidos-es.html Mice treated with azacitidine (demethylating agent) experienced a 60% reduction in tumors, and those treated with celecoxib (anti-inflammatory agent), a 77%.

15. MEDICAL UTILITY Adaptation is the mainstay of life and evolution, cells are adapted all the time to stay alive and be healthy.
