The formation of alternative DNA secondary structures can result in DNA breakage leading to cancer and other diseases. Chromosomal fragile sites, which are regions of the genome that exhibit chromosomal breakage under conditions of mild replication stress, are predicted to form stable DNA secondary structures. DNA breakage at fragile sites is associated with regions that are deleted, amplified ...
Fragile X syndrome is the most frequent form of inherited mental retardation and is associated with a fragile site at Xq27.3. We identified human YAC clones that span fragile X site-induced translocation breakpoints coincident with the fragile X site. A gene (FMR-1) was identified within a four cosmid contig of YAC DNA that expresses a 4.8 kb message in human brain. Within a 7.4 kb EcoRI genomi...
Abstract. Previous research demonstrates that membership of majority groups is often perceived as more fragile than minority groups. Four studies ( N 1 = 90, 2 247, 3 500, 4 1,176) investigated whether this was the case for heterosexual identity, relative to gay identity. Support heterosexuality found using various methods: sexual orientation perceptions a target who engaged in incongruent beha...
