The primary concern of cell division is the maintenance of the original cell's genome. Before division can occur, the genomic information that is stored in chromosomes must be replicated, and the duplicated genome must be separated cleanly between cells. A great deal of cellular infrastructure is involved in keeping genomic information consistent between generations.
Military discharge certificate. In the United States of America, every service member who is discharged or released from active duty is issued a DD Form 214, a military discharge certificate. A reservist who is called up to active duty is given a DD 214 when he or she is deactivated and returned to the reserves.

With you total military earnings and a copy of your DD-214 in hand, contact your HR office. You will need to complete one more form (SF-3108 or SF-2803).
