Abstract: A method of assembling large DNA fragments in a chromosome using site specific recombinases and alternating excisionases. The method may be performed in vitro or in vivo, but larger assemblies are possible when the assembly is performed in vivo. For an in vivo assembly, the cell must be engineered to contain the desired recombinases, each in an inducible construct so that the desired recombinase can be expressed at the correct time with the correct choice of inducing agent.

Abstract: Ralstonia solanacearum, the causal agent of bacterial brown rot of potato, is often carried latently in seed potato tubers. Primers and a probe were designed for a real-time BIO-PCR assay technique for detecting potato tubers latently infected with R. Solanacearum. Using naturally infected potato tubers, as few as 20 cells/ml extract could be detected. Two of 14 naturally infected potato tubers with no disease symptoms were positive by the newly described real-time BIO-PCR (pre-enrichment on agar or in liquid medium) assay but not by direct real-time PCR.

Abstract: Disclosed herein is a method for synthesizing a desired nucleic acid sequence. The method comprises dividing the desired sequence into a plurality of partially overlapping segments; optimizing the melting temperatures of the overlapping regions of each segment to disfavor hybridization to the overlapping segments which are non-adjacent in the desired sequence; allowing the overlapping regions of single stranded segments which are adjacent to one another in the desired sequence to hybridize to one another under conditions which disfavor hybridization of non-adjacent segments; and filling in, ligating, or repairing the gaps between the overlapping regions, thereby forming a double-stranded DNA with the desired sequence. Also disclosed is a method for preventing errors in the synthesis of the nucleic acid sequence.

Abstract: Disclosed are new methods comprising the use of in situ hybridization to detect abnormal nucleic acid sequence copy numbers in one or more genomes wherein repetitive sequences that bind to multiple loci in a reference chromosome spread are either substantially removed and/or their hybridization signals suppressed. The invention termed Comparative Genomic Hybridization (CGH) provides for methods of determining the relative number of copies of nucleic acid sequences in one or more subject genomes or portions thereof (for example, a tumor cell) as a function of the location of those sequences in a reference genome (for example, a normal human genome). The intensity(ies) of the signals from each labeled subject nucleic acid and/or the differences in the ratios between different signals from the labeled subject nucleic acid sequences are compared to determine the relative copy numbers of the nucleic acid sequences in the one or more subject genomes as a function of position along the reference chromosome spread.
