Abstract: Single-cell sequencing provides a new level of granularity in studying the heterogeneous nature of cancer cells. For some cancers, this heterogeneity is the result of copy number changes of genes within the cellular genomes. The ability to accurately determine such copy number changes is critical in tracing and understanding tumorigenesis. Current single-cell genome sequencing methodologies infer copy numbers based on statistical approaches followed by rounding decimal numbers to integer values. Such methodologies are sample dependent, have varying calling sensitivities which heavily depend on the sample's ploidy and are sensitive to noise in sequencing data. Described herein are novel methods for reconstructing the genome of a single cell.

Abstract: Provided are a washing machine and a washing drum thereof. The washing drum comprises a large container and a small container. The small container is detachably disposed in the large container, and an opening of the small container and an opening of the large container are positioned opposite to each other. In a washing process, clothes needing special care can be placed in the small container so that water in the large container does not enter the small container, thereby realizing separating washing of the clothes needing special care. If there are no clothes needing special care, the small container can be detached from the large container to perform a normal washing operation.

Abstract: In certain embodiments, the present invention provides a way of “digitally” marking different the alleles of different chromosomes by using a transposase to insert differently barcoded transposons into genomic DNA before further analysis. According to this method, each allele becomes marked with a unique pattern of transposon barcodes. Because each unique pattern of transposon barcodes identifies a particular allele, the method facilitates determinations of ploidy and copy number variation, improves the ability to discriminate among homozygotes, heterozygotes, and patterns arising from sequencing errors, and allows loci separated by uninformative stretches of DNA to be identified as linked loci, thereby facilitating haplotype determinations. Also provided is a novel artificial transposon end that includes a barcode sequence in two or more positions that are not essential for transposition.
