贵刊第 7期刊载的《DNA化学技术及展望》一文 ,关于人类基因组研究的一处说法欠妥。孙老师文章中说 ,人的细胞内有 46条染色体 ,上面含有约 1 0万个基因。一个基因就由约5 0 0 -2 0 0 0个DNA分子组成 ,所以 ,一个人基因组包含的配对核苷酸则多达 30亿对。而《普通生物学?
The article titled “DNA Chemistry Technology and Prospects” published in the 7th issue of your journal is not proper regarding one aspect of human genome research. According to Sun’s article, there are 46 chromosomes in the human cell, which contains about 10 000 genes. A gene consists of about 500–200 DNA molecules, so a human genome contains up to 3 billion pairs of matched nucleotides. And "general biology?
