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.
If you qualify and take the proper steps you can apply for a review of discharge and possibly have it changed. Each of the military services maintains a discharge review board with authority to change, correct or modify discharges or dismissals that are not issued by a sentence of a general courts-martial. The board has no authority to address medical discharges. The veteran or, if the veteran is deceased or incompetent, the surviving spouse, next of kin or legal representative may apply for a review of discharge by writing to the military department concerned, using DoD Form 293.
