| 摘要 |
The invention provides methods and compositions for sequencing DNA or RNA samples that would be impossible to do via standard means. Samples that are part of mixtures or are degraded or modified may be sequenced so that the individual from whom the sample originated can be determined or useful biological information can be associated with the sample. Methods are described that allow high efficiency sequencing of degraded nucleic acid samples such as are typically found with FFPE. Samples from severely degraded sources or that have been treated with preservatives such as formalin may be sequenced. In addition to permitting identification of samples, information about disease or treatment status may also be determined.
