TīmeklisEfficient site-directed insertion of heterologous DNA into a genome remains an outstanding challenge. Recombinases that can integrate kilobase-sized DNA constructs are difficult to reprogram to user-defined loci, while genomic insertion using CRISPR-Cas methods relies on inefficient host DNA repair … DNA recombinases are widely used in multicellular organisms to manipulate the structure of genomes, and to control gene expression. These enzymes, derived from bacteria (bacteriophages) and fungi, catalyze directionally sensitive DNA exchange reactions between short (30–40 nucleotides) target … Skatīt vairāk Recombinases are genetic recombination enzymes. Skatīt vairāk • Recombinases at the U.S. National Library of Medicine Medical Subject Headings (MeSH) Skatīt vairāk Recombinases have a central role in homologous recombination in a wide range of organisms. Such recombinases have been described in archaea, bacteria, eukaryotes and viruses. Archaea The archaeon Skatīt vairāk

Tīmeklis2006. gada 13. jūn. · The amplification of DNA is an essential step in most nucleic acid–based testing strategies. Established amplification techniques rely on sophisticated instrumentation, such as temperature-regulating equipment or complex sample-handling procedures. While unproblematic for specialised laboratories, these requirements … Tīmeklis2001. gada 1. jūn. · To compare the function of FLP and Cre recombinases in Xenopus embryos, we designed the Cre inducible reporter CMV:GFP (loxP)lacZ (Fig. 4 A) … Tīmeklis2006. gada 19. maijs · The Cre-lox and FLP-FRT systems. JAX NotesMay 19, 2006. Two of the most exciting and versatile genetic tools designed in the last 30 years are the Cre-lox and FLP-FRT technologies. Both allow the location and timing of gene expression to be closely regulated. This article briefly outlines how the two systems … theodore lucas miami
