โœฆ Synopsis

This is a review summarizing work carried out at the Laboratory of Molecular Cytogenetics in recent years. Problems of genetic organization of bands, interbands and puffs as well as intercalary heterochromatin and position effect variegation are discussed from the point of view of the dynamic model of polytene chromosome organization.

The concept of the structural and functional organization of polytene chromosomes is formulated. It is based on the following:Interbands are transcriptional active chromosome regions; they seem to be responsible for the base metabolism of the cell. The stability of these metabolic processes in the c

A pachytene chromomere map of bivalent 10 is presented. Recent results from high-resolution metaphase banding document a similar pattern of intrachromosomal differentiation.
