51.   Some researchers say the genes make a protein that hears commands for the cancer cell to grow.

52.   So if a tumor or virus makes a protein that also appears on brain cells, the immune system will hunt down and attack those cells as well.

53.   Sometimes, perhaps because of signals from the introns that have yet to be identified, certain exons are skipped, and a different protein is made.

54.   Taken together, these genes comprises all the information for making proteins which build and operate the body.

55.   The ability to make different proteins from the same gene is known as alternative splicing.

56.   That material is designed to stop the Philadelphia chromosome from directing cells to make a protein that leads to cancerous growth.

57.   The daughter genes can then be inserted into bacteria or fungi, where they begin making protein.

58.   The DNA is then supposed to cause proteins to be made in the right place and in the right amount.

59.   The gene studied by the Italian researchers makes a protein that forces the cell to die when oxygen damage is detected.

60.   The gene makes a protein with a deadly role.
