In your assigned readings, you learned how cells divide in order to replace damaged and dead cells. Normally, division is regulated resulting in healthy functional tissue. Cancer occurs when normal regulation of cell division is lost and becomes uncontrolled. Uncontrolled division results in massive reproduction of abnormal cells. Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms that regulate the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should. Any disruption of the monitoring system can allow other mistakes to be passed on to the daughter cells. Each successive cell division will give rise to daughter cells with even more accumulated damage. Eventually, all checkpoints become nonfunctional, and rapidly reproducing cells crowd out normal cells, resulting in a tumor or leukemia (blood cancer).

hree-page summary of a video entitled “Cracking the code of life” (http://www.pbs.org/wgbh/nova/body/cracking-the-code-of-life.html).(It is only take about 3minutes, please watch it) Your summary should be double-spaced, font 12, 1-inch margin, and in Times New Roman. Your summary will consist of three sections: Introduction (10pts), summary (20pts), and conclusion (10pts). The summary section MUST include the following: 1) at least 1 story from the movie; 2) 1-2 advantages and disadvantages of the Human Genome Project. The term paper needs to have your name, course name, course number, date, and the title of your summary. You need to check for spelling and grammar before submission. Points will be taken off for not following directions above. No late paper will be graded.
