Publisher Summary This chapter discusses the functional aspects of satellite DNA and
heterochromatin. Despite all attempts to formulate simple rules governing satellite evolution …

Publisher Summary This chapter reviews the morphology and structure of polytene
chromosomes. The chapter focuses on the gene map** and building of cytogenetic maps …

Publisher Summary This chapter describes that the problems relating to the organization of
heterochromatin are prominent in the general thinking about the organization of genetic …

Publisher Summary The interphase polytene chromosome is morphologically differentiated
into tightly compacted (the chromomeric) and decompacted (the interchomomeric) regions …

We found that the sex-ratio of an amphigenic strain of Sciara ocellaris varied widely from
progenies with few males to progenies containing a larger proportion of males, with single …

In Drosophila hydei, as in other Dipteran species, numerous puffs can be observed along
the polytene chromosomes in larval and in some adult cell types. Each of these puffs …

Since the Russian edition of this book was published in 1975 many new research works
have appeared which have made necessary some additions for the English edition, to reflect …

The DNA methylation pattern of Vicia faba metaphase chromosomes was examined with a
specific monoclonal antibody. 5-methylcytosine (5-mC) residues are present in different …

Nuclear division and migration of cleavage nuclei in the embryos of Bradysia tritici (Diptera:
Sciaridae) have been studied by light microscopy and nuclear staining. There are 8 …

Cytological maps of the four polytene elements of Sciara pauciseta II, at two different stages
of DNA puff development, have been prepared. A detailed description of major …
