Abstract
Chromosome 17ps was identified in the mother and daughter but not the father of a normal family with no history of congenital abnormality. In addition to G-band and Ag-NOR staining, previously used to study this abnormality, we applied N-band and C-band techniques. Our results showed that 17ps has no demonstrable ribosomal cistron or constitutive heterochromatin.
摘要
在一个无先天性异常家族史的正常家庭中，母亲和女儿被检测出17号染色体短臂异常，而父亲未检测到。除了之前用于研究这种异常的G带和银染核仁组织区染色外，我们还应用了N带和C带技术。我们的结果表明，17号染色体短臂没有可证明的核糖体顺反子或组成型异染色质。
