基因转型(gene－transformation)
目的带有特定基因的质体在分子生物研究上，是一个很重要的工具，将质体送入细菌的过程称为基因转形，经由基因转型可使质体在细菌中大量复制，以备进一步研究。本实验将把你在前面转殖实验中cDNA和质体DNA的连结反应送入细菌。 你将从本实验学习如何进行基因转型作用。原理早在1970年左右，有人发现细菌经由冰冷

如果你最近还没有为你的猫咪做检查，那你也可能不知道你的猫咪可能感染了艾滋病毒。猫免疫缺陷病毒肯能会引起猫咪致病，其症状类似感染HIV病毒后的症状。但是科学家认为这是研究抗HIV新药的一种契机。 猫咪会怎么帮助人们抗击艾滋病呢？不管是猫免疫缺陷病毒（FIV)还是人免疫缺陷病毒都会依赖一种称为整合
Structure封面文章：解密白内障的形成
白内障是致盲的第一杀手，目前世界上有近两千万人受到它的影响。日前，加州大学Irvine分校的科学家们取得了重要成果，揭开了白内障的形成机制，这一成果将有望帮助人们为白内障患者恢复视力。这项研究作为封面文章刊登在十二月的Structure杂志上。 “我们的研究阐述了白内障形成的分子机制，这一
蛋白质结构预测(protein－structure－prediction)
一种生物体的基因组规定了所有构成该生物体的蛋白质，基因规定了组成蛋白质的氨基酸序列。虽然蛋白质由氨基酸的线性序列组成，但是，它们只有折叠成特定的空间构象才能具有相应的活性和相应的生物学功能。了解蛋白质的空间结构不仅有利于认识蛋白质的功能，也有利于认识蛋白质是如何执行其功能的。确定蛋白质的结构对于生物
