Background Recently, we analyzed genome-wide protein binding data for the Drosophila cell lines S2, Kc, BG3 and Cl.8 (modENCODE Consortium) and identified a set of 12 proteins enriched in the regions corresponding to interbands of salivary gland poly

In Drosophila melanogaster, the chromatin of interphase polytene chromosomes appears as alternating decondensed interbands and dense black or thin gray bands. Recently, we uncovered four principle chromatin states (4НММ model) in the fruit fly, an

Here we demonstrate the feasibility of a novel approach to quantify DNA in cell nuclei. This approach is based on spectroscopy analysis of Raman light scattering, and avoids the problem of nonstoichiometric binding of dyes to DNA, as it directly meas

Mechanisms of chromatin decompaction in interbands of Drosophila polytene chromosomes have been studied. Using the example of interband 3C6/C7 of the X chromosome, we investigated the ability of different DNA segments to form an interband in a new ge

The genome size of Cyclops in cells at early stages of cleavage (up to the fifth division) and in somatic cells was estimated by static digital Feulgen cytophotometry in order to study quantitative changes in DNA content during chromatin diminution.

Overexpression of Suppressor of Underreplication protein (SUUR) induces giant reversible swellings in intercalary and pericentric heterochromatin of salivary gland polytene chromosomes. Here, we demonstrate that morphology and extent of swellings are
