Localization of RNA polymerase in polytene chromosomes of Drosophila melanogaster.
RNA polymerase (RNA nucleotidyltransferase) B (or II) and histone H1 of Drosophila melanogster were localized on salivary gland polytene chromosomes using the indirect immunofluorescence technique. RNA polymerase B is present almost exclusively in puffs and interband regions, whereas histone H1 is found primarily in bands. The puff at region 3C, known to be transcriptionally active in larval sa...

15 صفحه اولGenetic Analysis of the Antennapedia Gene Complex (Ant-C) and Adjacent Chromosomal Regions of DROSOPHILA MELANOGASTER. II. Polytene Chromosome Segments 84A-84B1,2.
The existence of a gene complex in the proximal right arm of chromosome 3 of Drosophila melanogaster involved in the development of the head and thorax was originally suggested by the phenotypes of several dominant homoeotic mutations and their revertants. A screen for mutations utilizing Df(3R) Antp(Ns+R17) (proximally broken in salivary region 84B1,2) yielded, among 102 recovered mutations, 1...
متن کاملLocalization of ecdysterone on polytene chromosomes of Drosophila melanogaster.
Ecdysterone has been crosslinked in situ to polytene chromosomes of salivary glands of Drosophila melanogaster by photoactivation. The crosslinked hormone has been localized on the chromosomes by indirect immunofluorescence microscopy. At different developmental stages the hormone was detected at different chromosomal loci. These chromosomal sites correspond to ecdysterone-inducible puff sites....
متن کاملGenetic analysis of the brahma gene of Drosophila melanogaster and polytene chromosome subdivisions 72AB.
The brahma gene is required for activation of the homeotic genes of the Antennapedia and bithorax complexes in Drosophila. We have isolated and characterized 21 mutations in brahma. We show that both maternal and zygotic functions of brahma are required during embryogenesis. In addition, the severe abnormalities caused by loss of maternal brahma expression show that the homeotic genes are not t...
