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… (More)
