Distribution of repetitive DNA sequences in the polytene chromosomes of Rhynchosciara americana.

G M Machado-Santelli, M F Bonaldo, R V Santelli, R A Eckhardt, F J Lara.   

Abstract

The distribution of fast, intermediate and slow renaturing fractions of Rhynchosciara americana DNA was examined in the polytene salivary gland chromosomes by in situ hybridization. Heterochromatic areas readily hybridized but hybrid formation in the euchromatin depended more on the repetitiveness of the RNA probe.
