2002年诺贝尔生理学医学奖授予3位科学家，这3位科学家发现了在器官发育和“程序性细胞死亡”过程中的基因规则。这项工作对人类战胜疾病将发挥重大作用。请回答下面的问题：

(1)细胞凋亡是指________。由于受到严格的遗传机制的调控，这些细胞死的有规律，似乎是按编好了的“程序”进行的，所以又被称为_________，控制细胞凋亡的遗传物质主要位于_____________。

(2)人的胚胎在发育初期是有尾的，但在胚胎发育过程中失去尾，这是由于______________。

(3)研究发现人的神经系统在发育过程中，约有50%的细胞发生程序性死亡。那么，人的表皮中具有调控程序性死亡的基因吗？为什么？

(4)如果该死亡的细胞没有死亡，不该死亡的细胞大批死亡，人就会患病，如癌症、艾滋病等。请你对未来癌症、艾滋病的治疗进行大胆的设想。
