J. Delatorre et al., PATTERNS OF DNASE-I SENSITIVITY IN THE CHROMOSOMES OF THE GRASSHOPPERCHORTHIPPUS-PARALLELUS (ORTHOPTERA), Chromosome research, 4(1), 1996, pp. 56-60
We have analysed the patterns of DNase I/nick translation in the chrom
osomes of the grasshopper Chorthippus parallelus erythropos. Sites of
preferential DNase I-nicking were concentrated at the distal chromosom
e regions, thus showing the non-uniform DNase I sensitivity of differe
nt chromosome domains. Among centromeric C-bands, the heterochromatin
of metacentric and acrocentric chromosomes differed with respect to th
eir DNase I resistance.
