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.
DD Form 214, Discharge Papers and Separation Documents. A Report of Separation is generally issued when a service member performs active duty or at least 90 consecutive days of active duty training. The Report of Separation contains information normally needed to verify military service for benefits, retirement, employment and membership in veterans' organizations. The report of separation form issued in most recent years is the DD Form 214, Certificate of Release or Discharge from Active Duty. Before January 1, 1950, several similar forms were used by the military services, including the WD AGO 53, WD AGO 55, WD AGO 53-55, NAVPERS 553, NAVMC 78PD and the NAVCG 553.
