得到的主要结果和结论如下： 1，通过用去乙酰化酶抑制剂处理果蝇幼虫，观察果蝇多线染色体在热休克基因处的形态变化，发现去乙酰化酶抑制剂介导的乙酰化水平的升高可引起染色体结构的显著变化，推测乙酰化修饰不仅影响分子间的相互作用而且还可以影响染色体的高级结构。

The protocol is summarized in Figure 18.16. A radioactive probe representing a gene (most often a labeled cDNA clone derived from the mRNA) is hybridized with thedenatured DNA of the polytene chromosomes in situ. Autoradiography identifies the position or positions of the corresponding genes by the superimposition of grains at a particular band or bands.
