| 1 | The complete mitochondrial genomes sequences of Asio flammeus and Asio otus and comparative analysis显示文摘The complete mitochondrial genomes of Asio flammeus and Asio otus were se- quenced and found to span 18858 bp and 18493 bp, respectively. It is surprising to find the for- mer to be the largest among all avian mitochondrial genomes sequenced so far. The two ge- nomes have very similar gene order with that of Gallus gallus, neither contains the pseudo con- trol region, but both have a single extra base, namely Cytidine, at position 174 in ND3 gene. The control regions of Asio flammeus and Asio otus’ mitochondrial genomes span 3288 bp and 2926 bp respectively, which are the longest among vertebrates except for Myxine glutinosa and con- tribute to the large size of two genomes. The 3′end of the control region of Asio flammeus and Asio otus contains many tandemly repeated sequences, which are highly similar to a putative control element, i.e. Mt5, and may form stable stem-loop secondary structures. Such repeated sequences probably play an important role in regulating transcription and replication of mito- chondrial genome. Our results may provide important clues for uncovering the origin and evolu- tion mechanisms of mitochondrion genome. | SUN Yi1, MA Fei1, XIAO Bing1, ZHENG Junjie2, YUAN Xiaodong2, TANG Minqian2, WANG Li3, YU Yefei3 & Li Qingwei1 1.

| 16 | 抓图小法显示文摘上网的时候看到漂亮的图片(比如PLMM的照片),想把它保存在自己的电脑里。这时就可以在图片上右键单击,选择“图片另存为”就可以保存下来了。 遇到网页禁止下载图片或者是光盘上无法拷贝图片的时候,怎么办呢?键盘上有一个键你是不是从来没用过?它可以完成抓图任务。抓字?抓字也成,反正屏幕上有什么它就抓什么,因为它就是抓屏键Print | SNAKE | 2003 | 电脑爱好者2003,,9: | 0 |

| 18 | 后PC时代的主力——笔记本电脑的普及离我们还有多远?显示文摘细心的读者朋友不难发现,最近刊登于各大媒体上的笔记本电脑广告似乎多了起来,身边也有一些人开始背着“本”上班了。仔细看看广告就可以发现,一台配置并不差的笔记本电脑的价格甚至已经跌到了万元以下,这似乎很难使人克制自己购买一台笔记本电脑的冲动。为什么现在笔记本电脑这么便宜?我到底有没有买一台笔记本电脑的必要?下面我们就从技术以及市场需求两个方面来分析一下这个问题。 | Solid Snake | 2002 | 电脑爱好者2002,,14: | 0 |
