1970年以来,重要的技术改进已经使得人类细胞遗传学发生真正的革命,它的应用越来越广,它的精确性越来越高。全新的领域一个接着一个地被开拓。总而言之,人类细胞遗传学和哺乳动物细胞遗传学再也不是纯粹的描述性技术了。很多基因的位点现已被确定,并且染色体上一些区段的作用、复制及钝化的秘密将逐渐被揭开。本会议的目标是评论细胞遗传学某些领域的最近发展。 Sperling介绍了染色体成熟前固缩现象(premature chromosome condensation,PCC):中期和间期细胞的融合,造成间期染色体的固缩。在微核细胞中,单一染色体也可看到这种现象。这样便可用光学显微镜
Since 1970, significant technological improvements have led to a true revolution in human cytogenetics, its use is becoming more and more widespread, and its accuracy is increasing. New areas one by one to be opened up. All in all, human cytogenetics and mammalian cytogenetics are no longer purely descriptive techniques. The location of many genes has now been identified and the role of some segments of the chromosome, the secret of replication and passivation, will gradually unravel. The goal of this conference is to comment on recent developments in some areas of cytogenetics. Sperling introduced the premature chromosome condensation (PCC) of chromosomes: the fusion of metaphase and interphase cells, resulting in the shrinkage of interphase chromosomes. In the micronucleus cells, a single chromosome can also see this phenomenon. This can be used optical microscope
