[单项选择]3. A Gay Biologist
Molecular (分子的) biologist Dean Hammer has blue eyes ,light brown hair and a good sense of humor. He smokes cigarettes, spends long hours in an old laboratory at the US National Institute of Health. He also happens to be openly, matter - of - factly gay.
What is it that makes Hammer who he is What accounts for the talents and traits that make up anyone’s personality Hammer is not content merely to ask such questions; he is trying to answer them as well. A pioneer in the field of molecular psychology, Hammer is exploring the role genes play in governing the very core of our individuality. To a remarkable extent, his work on what might be called the gay, thrill--seeking and quit--smoking genes reflects how own genetic predispositions(倾向).
That work, which has appeared mostly in scientific journals, has been gathered into an accessible and quite readable form in Hammer’ s creative new book, Living with Our Genes. "vou have about as much ch

[简答题]形态标记(morphological marker)和分子标记(molecular marker)都可用于基因定位，简要说明利用这两种标记进行基因定位的基本步骤。
[简答题]The Ras protein functions as a molecular switch that is set to its onstate by a guanine-nucleotide exchange factor (GEF) that causes it to bind GTP. A GTPase-activating protein (GAP) resets the switch to the off state by inducing Ras to hydrolyze its bound GTP to GDP much more rapidly than in the absence of the GAP. Thus Ras works like a light switch that one person turns on and another turns off. In a cell line that lacks the Ras-specific GAP, what abnormalities would you expect to find in the way Ras activity responds to extracellular signals
[单项选择]根据分子动理论，设两个分子间的距离为r0时分子间的引力和斥力相等，以下关于分子力与分子势能与它们间距离的关系，正确的是( )。
A. 若两分子间距离在r0的基础上增大，则分子间的引力增大，斥力减小，分子力表现为引力
B. 两分子间距离越大，分子力越小；分子间距离越小，分子力越大
C. 两分子间距离为r0时，分子势能最小，在r0的基础上距离增大或减小，分子势能都变大
D. 两分子间距离越大，分子势能越大；分子间距离越小，分子势能越小
