    摘要: Compositions and methods for analysis of nucleic acids are disclosed. Targets are hybridized to arrays having features that include pairs of co-localized probes within features. The probe pairs may include a first probe type that is oriented so that the 5′ end is free and the 3′ end is attached to the support and a second probe type that is oriented so that the 3′ end is free for extension and the 5′ end is attached to the support. The probes of a feature are complementary to different regions of the same target sequence so they can simultaneously hybridize to a single target with a gap or nick between. The gap may be filled by extension and ligation or ligation.
