热点之一:关注生物科学的最新进展,关注这种进展的科学意义、生产价值和社会现实意义,重点考查这些热点中蕴涵的基础知识。细胞工程技术和微生物发酵工程技术是当代生物科学应用的一个热点,这种热点在高考中也有充分的体现。例1(2004年高考湖南卷)用动物细胞工程技术获取单克隆抗体,下列实验步骤中错误的是(B)。
One of the hot spots: pay attention to the latest developments in the biological sciences, pay attention to the scientific significance, production value and social reality significance of this progress, and focus on examining the basic knowledge contained in these hot spots. Cell engineering technology and microbial fermentation engineering technology is a hot topic in contemporary biological sciences. This hot spot is also fully reflected in the college entrance examination. Example 1 (Hunan College Entrance Examination, 2004) The monoclonal antibody was obtained using animal cell engineering techniques. The error in the following experimental steps was (B).
