Because humans have an inherent need to 1 uncertainty, according to a recent study in Psychological Science. The new research reveals that the need to know is so strong that people will 2 to satisfy their curiosity even when it is clear the answer will 3 .

In a series of four experiments, behavioral scientists at the University of Chicago and the Wisconsin School of Business tested students’willingness to 4 themselves to unpleasant stimuli in an effort to satisfy curiosity. For one 5 each participant was shown a pile of pens that the researcher claimed were from a previous experiment. The twist?Half of the pens would 6 an electric shock when clicked.

Twenty-seven students were told which pens were electrified; another twenty-seven were told only that some were electrified 7 left alone in the room, the students who did not know which ones would shock them clicked more pens and incurred more shocks than the students who knew what would 8 . Subsequent experiments reproduced this effect with other stimuli, 9 the sound of fingernails on a chalkboard and photographs of disgusting insects.

The drive to 10 is deeply rooted in humans, much the same as the basic drives for 11 or shelter, says Christopher Hsee of the University of Chicago. Curiosity is often considered a good instinct-it can 12 new scientific advances, for instance-but sometimes such 13 can backfire. The insight that curiosity can drive you to do 14 things is a profound one. Unhealthy curiosity is possible to 15 , however. In a final experiment, participants who were encouraged to 16 how they would feel after viewing an unpleasant picture were less likely to 17 to see such an image. These results suggest that imagining the 18 of following through on one’s curiosity ahead of time can help determine 19 it is worth the endeavor. Thinking about long-term 20 is key to reducing the possible negative effects of curiosity." Hsee says. In other words, don’t read online comments.

下列对逆转录的叙述错f的是
A.以RNA为模板合成双链DNA B.逆转录的合成原料为4种dNTP
C.逆转录与转录相似,均不需要引物 D. RNA: DNA杂化双链为过程的中间产物

答案:C
解析:
[考点]逆转录及逆转录酶 [分析]逆转录也称反转录,是依赖RNA的DNA合成过程,以RNA为模板,以4种dNTP为原料合成双链DNA分子合成反应也是从5'向3'延伸新链,合成过程中是需要引物的,现在认为其引物是病毒本身的一种tRNA,这是与转录不同的。在反应过程中以RNA为模板先合成一条单链DNA,这样模板与产物形成RNA: DNA杂化双链,这只是个中间产物,此后逆转录酶(RNA酶 活性部分)催化RNA水解,余下产物单股 DNA链,最后逆转录酶(DNA聚合酶活性部分)再催化DNA合成。
