Above all, the type of band is determined by the period of the phase S in which the cell was at the time of the treatment by BrdU. Thus the coexistence of many types of banding may be explained here by the great variability of the cellular cycle of the lymphocytes in culture.</p>","PeriodicalId":75916,"journal":{"name":"Humangenetik","volume":"30 4","pages":"297-306"},"PeriodicalIF":0.0,"publicationDate":"1975-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11278343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is an apparent lack, however, of inverted acro- or subtelocentric No. 9 reported in the literature. This obvious difference in the break points on chromosome 9 is most likely due to 1. hot-spots for chromosome breakage i.e. highly susceptible regions such as the euchromatic-heterochromatic junctions. 2. a higher degree of elimination against such acro- or subtelocentric chromosomes from one generation to the other.</p>","PeriodicalId":75916,"journal":{"name":"Humangenetik","volume":"30 4","pages":"287-9"},"PeriodicalIF":0.0,"publicationDate":"1975-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12395802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
