Abstract

The precise genomic localization of the borders of 62 intercalary heterochromatin bands in Drosophila polytene chromosomes was determined. A new type of bands containing chromatin of different states was identified. This type is a combination of the gray band and the intercalary heterochromatin band, creating a genetic structure that with a light microscope is identified as a continuous band. The border structure of such bands includes the coding regions of genes with ubiquitous activity.

摘要

确定了果蝇多线染色体中62条居间异染色质带边界的精确基因组定位。鉴定出一种包含不同状态染色质的新型带。这种类型是灰色带和居间异染色质带的组合，形成一种在光学显微镜下被识别为连续带的遗传结构。此类带的边界结构包括具有普遍活性的基因的编码区。
