京都大学讲师秀人山岸和日本电子公司最近成功地发明了一种用电子显微镜直接观察生命体的基本物质DNA结构的技术,从而为日本在现代生命科学研究领域的激烈竞争中赢得了重要的一分。DNA即脱氧核糖核苷酸,其原子大小大约仅20埃(1埃=10~(-8)厘米),迄今为止对它用电子显微镜直接观察的努力均告失败,主要原因就在于电子束破坏了DNA分子键,所以不能观察到原DNA原有的空
Kyoto University lecturer Hideki Yamane and Nippon Electric have recently succeeded in inventing a technology that uses electron microscopy to directly observe the DNA structure of the essential substance of living beings and thus have won an important one for Japan in the fierce competition in the field of modern life sciences Minute. DNA, a deoxyribonucleotide, has an atomic size of only about 20 angstroms (1 angstrom = 10 ~ (-8) cm). So far its efforts to observe directly by electron microscopy have all failed due to electron beam damage DNA molecular bond, so can not be observed original original DNA empty
