人类基因组计划冷泉港，纽约--生物学家长期以来一直认为，生物体越复杂，基因就越多。但上周在这里举行的一次会议上，普遍接受的人类基因数量为8万至10万的说法受到了打击，来自德国、美国和法国的研究人员提出了对基因数量的修正估计--所有这些估计都远低于5万。这些谈话，其中一些将发表在6月出版的《自然遗传学》上，引发了激烈的争论，至少有一位基因学家提出了一个新的10万多人的估计。
HUMAN GENOME PROJECTCOLD SPRING HARBOR, NEW YORK-- Biologists have long assumed that the more complex an organism is, the more genes it has. But last week at a meeting here, the generally accepted human gene count of 80,000 to 100,000 took a battering when researchers from Germany, the United States, and France offered revised estimates of the number of genes--all of them well below 50,000. The talks, some of which will be published in the June issue of Nature Genetics , sparked heated debates, with at least one genomicist countering with a new 100,000-plus estimate.
