The Organization of Pericentromeric Heterochromatin in Polytene Chromosome 3 of the <i>Drosophila</i> <i>melanogaster</i> Line with the <i>Rif1<sup>1</sup>; SuUR<sup>ES</sup> Su(var)3-9<sup>06</sup></i> Mutations Suppressing Underreplication

The Organization of Pericentromeric Heterochromatin in Polytene Chromosome 3 of the <i>Drosophila</i> <i>melanogaster</i> Line with the <i>Rif1<sup>1</sup>; SuUR<sup>ES</sup> Su(var)3-9<sup>06</sup></i> Mutations Suppressing Underreplication

Although heterochromatin makes up 40% of the <i>Drosophila melanogaster</i> genome, its organization remains little explored, especially in polytene chromosomes, as it is virtually not represented in them due to underreplication. Two all-new approaches were used in this work: (i) with th...
