人类的体细胞具有44条(22对)常染色体和两条性染色体组成,这些染色体上承载着人类3万~4万个的基因[1],每条染色体上的基因都有严格的排列顺序,如果发生基因的增加、缺失、重排都会导致疾病的发生。我们认识这些染色体经历了很长一段艰辛的历程,从开始认为数目为48条,到华裔学者将有兴在胎儿肺组织培养中得到正确结果为46条;从开始的非显带染色体到G显带染色体、高分辨染色体的识别,每一次的技术进步。都给我们带来
Human somatic cells have 44 (22 pairs) autosomes and two sex chromosomes, which carry 30,000 to 40,000 human genes [1]. The genes on each chromosome have a strict sequence , If the gene increases, deletions, rearrangements will lead to the occurrence of the disease. We know these chromosomes have gone through a long period of arduous journey, from the beginning that the number of 48, Chinese scholars will Xingxing fetal lung tissue culture in the right result was 46; from the beginning of the non-visible chromosome G With chromosomes, high-resolution chromosome recognition, every time the technological advances. Have brought us
