We describe a method for interrogating the content and primary structure of DNA by microarray analyses and to provide comprehensive genetic screening and diagnostics prior to embryo transfer within an IVF setting. We will accomplish this by the following claims: 1) an optimized embryo grading system, 2) a less invasive embryo biopsy with reduced cellular contamination, 3) an optimized DNA amplification protocol for single cells, 4) identify aneuploidy and structural chromosome abnormalities using microarrays, 5) identifying sub-telomeric chromosome rearrangements, 6) a modified DNA fingerprinting protocol, 7) determine imprinting and epigenetic changes in developing embryos, 8) performing genome-wide scans to clarify/diagnose multi-factorial genetic disease and to determine genotype/haplotype patterns that may predict future disease, 9) determining single gene disorders with or without a known DNA mutation, 10) determining mtDNA mutations and/or the combination of mtDNA and genomic (nuclear) DNA aberrations that cause genetic disease.

The subject invention provides novel plants that are not only resistant to 2,4-D, but also to pyridyloxyacetate herbicides. Heretofore, there was no expectation or suggestion that a plant with both of these advantageous properties could be produced by the introduction of a single gene. The subject invention also includes plants that produce one or more enzymes of the subject invention “stacked” together with one or more other herbicide resistance genes. The subject invention enables novel combinations of herbicides to be used in new ways. Furthermore, the subject invention provides novel methods of preventing the development of, and controlling, strains of weeds that are resistant to one or more herbicides such as glyphosate. The preferred enzyme and gene for use according to the subject invention are referred to herein as AAD-12 (AryloxyAlkanoate Dioxygenase). This highly novel discovery is the basis of significant herbicide tolerant crop trait and selectable marker opportunities.

The invention discloses a process of knocking out Wnt3a gene and a verification method thereof. The knockout and verification of Wnt3a gene are finished through the following steps: establishment of a Cas9 lentiviral vector for Wnt3a gene, culture and passage of HepG2 cell, lentivirus infection and screening of target cell, verification of gene knockout efficiency through a mispairing enzyme method, cell protein analysis and cell proliferation detection by a CCK-8 method. The invention has the following advantages: the Wnt3a gene is knocked out by establishing a Cas9 double-vector lentivirus system for the first time; Crispr/Cas9 is a technology for accurately editing specific site of the genome of any species, and the cell-level single gene or multiple genes can be knocked out by the technology; compared with other gene editing technologies, the method has the advantages that the targeting accuracy is higher; only if the RNA target sequence is completely matched with the genome sequence, can the Cas9 cut the DNA and realize simultaneous knockout of multiple sites of the target gene; and moreover, the experimental period of vector establishment is short, the time and the cost are remarkably saved, and species limit is avoided.

The invention discloses gene knockout and gene insertion on eukaryotic genomes carried out by two Cas proteins (Cas7 and Cas3) in a 1 class I type CRISPR-Cas system for the first time. The developmentof the method breaks the limitation of dependence on single-gene cas9 and cpf1, and provides a new perspective for performing gene editing on the eukaryotes by multi-gene. By applying the system, thegene editing can be conveniently, rapidly and effectively carried out on eukaryote brewer's yeast genomes. The optimized tool is expected to be widely used in the gene editing of other eukaryotes.

The present invention provides methods for enhanced detection of biological response patterns. In one embodiment of the invention, genes are grouped into basis genesets according to the co-regulation of their expression. Expression of individual genes within a geneset is indicated with a single gene expression value for the geneset by a projection process. The expression values of genesets, rather than the expression of individual genes, are then used as the basis for comparison and detection of biological response with greatly enhanced sensitivity. In another embodiment of the invention, biological responses are grouped according to the similarity of their biological profile.

The methods of the invention have many useful applications, particularly in the fields of drug development and discovery. For example, the methods of the invention may be used to compare biological responses with greatly enhanced sensitivity. The biological responses that may be compared according to these methods include responses to single perturbations, such as a biological response to a mutation or temperature change, as well as graded perturbations such as titration with a particular drug. The methods are also useful to identify cellular constituents, particularly genes, associated with a particular type of biological response. Further, the methods may also be used to identify perturbations, such as novel drugs or mutations, which effect one or more particular genesets. The methods may still further be used to remove experimental artifacts in biological response data.

The invention discloses a method and a system for intelligently interpreting and reporting the genetic variation of a single gene disease, which can automatically analyze the genetic variation resultbased on the original sequence data of a gene of a patient, and provide a professional genetic variation analysis report, thereby improving the diagnosis and treatment efficiency of the genetic variation.

The invention discloses a wnt16 gene deletion type zebra fish. Compared with the prior art, specific genes in the genome of a living body can be muted more efficiently and precisely; moreover, the manufacturing is simple, the cost is lower, multiple sites on target genes can be sheared at the same time, and any number of single gene can be muted. The wnt16 gene deletion type zebra fish can be applied to research related with gene and skeleton growth and other research for finding whether deletion of wnt16 gene is related with growth of other organs such as heart or not, and thus the wnt16 gene deletion type zebra fish has a good medical research value. At the same time, the growth period of zebra fishes without wnt16 gene is obviously shortened, and the wnt16 gene deletion type zebra fish also has a good commercial value therefore.
