    摘要: Haplotypes of one or more portions of a chromosome of an organism from sequencing information of DNA or RNA fragments can be determined. Heterozygous loci (hets) can be used to determine haplotypes. One allele on a first het can be connected (likely to be on the same haplotype) to an allele on a second het, thereby defining a particular orientation between the hets. Haplotypes can be assembled through these connections. Errors can be identified through redundant connection information, particularly using a confidence value (strength) for a particular connection. The connections among a set of hets can be analyzed to determine likely haplotypes for that set, e.g., an optimal tree of a graph containing the hets. Furthermore, haplotypes of different contiguous sections (contig) of the chromosome can be matched to a particular chromosome copy (e.g., to a particular parental copy). Thus, the phase of an entire chromosome can be determined.

    摘要: The present invention provides methods of making and using self-assembled arrays of single polynucleotide molecules for carrying out a variety of large-scale genetic measurements, such as gene expression analysis, gene copy number assessment, and the like. Random arrays used in the invention are “self-assembled” in the sense that they are formed by deposition of polynucleotide molecules onto a surface where they become fixed at random locations. The polynucleotide molecules fixed on the surface are then identified by direct sequence determination of component nucleic acids, such as incorporated probe sequences, or by other decoding schemes. Such identification converts a random array of determinable polynucleotides, and their respective probes into an addressable array of probe sequences.

    摘要: Methods are provided for efficient shotgun sequencing to allow efficient selection and sequencing of nucleic acids of interest contained in a library. The nucleic acids of interest can be defined any time before or after preparation of the library. One example of nucleic acids of interest is missing or low confidence genome sequences resulting from an initial sequencing procedure. Other nucleic acids of interest include subsets of genomic DNA, RNA or cDNAs (exons, genes, gene sets, transciptomes). By designing an efficient (simple to implement, speedy, high specificity, low cost) selection procedure, a more complete sequence is achieved with less effort than by using highly redundant shotgun sequencing in an initial sequencing procedure.
