本刊记者从1997年1月6日国家科委、中国科学院和上海市人民政府联合召开的新闻发布会上获悉,以中国科学院上海生物化学研究所洪国藩研究员为首的科学家,首次在世界上构建水稻基因组物理全图成功,这是中国在基础科学研究领域的又一重大突破,并在国际上受到同行的高度评价。基因是控制生物遗传性状的基本因子,其化学本质是一段DNA(脱氧核糖核酸)序列。基因组是一个生物体遗传信息的总和。人的基因组由30亿个核苷酸组 Our reporter learned from a press conference jointly held by the State Science and Technology Commission, Chinese Academy of Sciences and the Shanghai Municipal People’s Government on January 6, 1997 that scientists headed by researcher Hong Guofan from the Shanghai Institute of Biochemistry, Chinese Academy of Sciences, for the first time built rice in the world The success of the genome physics map is another major breakthrough for China in the field of basic scientific research and is highly praised by its peers in the world. Gene is the basic factor controlling biological traits, the chemical nature of a DNA (DNA) sequence. The genome is the sum of the genetic information of an organism. The human genome consists of 3 billion nucleotides
