Chromosome structure at interfaces between major chromatin types:Alpha‐ andBeta‐heterochromatin

摘要

AbstractThe chromocenter ofDrosophilapolytene chromosomes, which consists of two major chromatin types, has long been a troublesome region in molecular terms. The recent microcloning of part of this region, the isolation of a monoclonal antibody to abeta‐heterochromatin binding protein, and newin situstudies now shed a little more light on this chromosomal regio
