A new puffing pattern induced by temperature shock and DNP in drosophila

TL;DR: The results show that the two cloned Dm DNA segments derive from nonoverlapping regions of the Dm genome; that they contain homologous regions present once in 56H8 and twice in 132E3; and that each homologueous region is composed of three distinct contiguous sequence elements, x, y and z, which together define a 3 kb common unit.

TL;DR: The family of genes encoding heat shock proteins of about 70 kDa (hsp70) in vertebrates is reviewed under genetic aspects and general characteristics of the organization and evolution of the multigene family are discussed.

TL;DR: The study shows that topologically associating domains and compartment structures remain remarkably unchanged upon acute HS in human and Drosophila, while only modest changes of distal regulatory interactions are observed in human cells, suggesting that the chromatin conformation necessary for a robust HS response is preestablished in NHS cells of diverse metazoan species.

TL;DR: The evolving evidence that heat shock proteins are present in the extracellular environment, that reactivity to heatshock proteins does not necessarily reflect adverse, pro-inflammatory responses and that the promotion of reactivityto self-heat shock proteins can downregulate pathogenic processes all suggest a potential role for heat shock protein as therapeutic agents, rather than as therapeutic targets.

TL;DR: Polytene chromosomes in cells of salivary gland, Malpighian tubules and intestine of Rhynchosciara angelae are very favorable for study and experimental evidence suggests that a gene is located within a band, which may be morphological evidence of gene activities.

TL;DR: None of these investigations provide information as to the precise localization of structures within the nucleus which synthesize this acid, except the nucleolus, nor has it been shown that it is the nucleolar organizer which synthesizes the nucleolars ribonucleic acid.

TL;DR: The uptake of tritiated uridine, leucine and thymidine by salivary cell components of Smiftia appears to be a favourable one for cytochemical work on nuclear RNA's.

TL;DR: Als Kontrolle wird die zweite Speicheldrüse der zur Gewinnung von Kernen benutzten Larven für 3 Std als Ganzes in Ringer-Lösung bzw.
