Abstract
The distribution of fast, intermediate and slow renaturing fractions of Rhynchosciara americana DNA was examined in the polytene salivary gland chromosomes by in situ hybridization. Heterochromatic areas readily hybridized but hybrid formation in the euchromatin depended more on the repetitiveness of the RNA probe.
摘要
通过原位杂交技术，研究了美洲大蠊DNA的快速、中间和慢速复性组分在多线唾液腺染色体中的分布情况。异染色质区域很容易杂交，但常染色质中杂交体的形成更多地取决于RNA探针的重复性。
