Ordered arrangement of chromosomes
WebAbstract The question of chromosome distribution in the mammalian nucleus is addressed, and data are provided in support of the ordered arrangement of chromosomes in the Chinese hamster spermatocyte. Testicular cells were dispersed and air-dried without prior fixation, then stained and karyotyped. WebExamination of these organisms' chromosomes provided an explanation for the appearance of novel linkage groups; specifically, new chromosomes had appeared, and existing …
