摘要：
The terminal 240 kb of a human 2q telomere region was cloned in two overlapping yeast artificial-chromosomes (YACs). This DNA contains a region of low-copy subtelomeric repeats (within 50 kb of the 2q telomere), a segment of DNA duplicated on distal 8p23 (100 kb from the 2q telomere), and a region of single-copy DNA (230 kb from the 2q telomere). Two CpG islands are present in the DNA segment duplicated on distal 8p23. RecA-assisted restriction endonuclease cleavage of genomic DNA samples revealed a potential 55 kb chromosome length polymorphism at the 2q telomere. This work provides telomeric closure of maps for human chromosome 2q, demonstrates a novel, subtelomere-specific DNA duplication, and will permit detailed molecular and cytological studies of this human telomere region.
