  2. Site-specific recombination - Wikipedia

    en.wikipedia.org/wiki/Site-specific_recombination

    Site-specific recombination, also known as conservative site-specific recombination, is a type of genetic recombination in which DNA strand exchange takes place between segments possessing at least a certain degree of sequence homology. [1] [2] [3] Enzymes known as site-specific recombinases (SSRs) perform rearrangements of DNA segments by ...

  3. QR code - Wikipedia

    en.wikipedia.org/wiki/QR_code

    The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...

  4. Cre-Lox recombination - Wikipedia

    en.wikipedia.org/wiki/Cre-Lox_recombination

    The Cre-lox system is used as a genetic tool to control site specific recombinationevents in genomic DNA. This system has allowed researchers to manipulate a variety of genetically modified organisms to control gene expression, delete undesired DNA sequences and modify chromosome architecture. The Creprotein is a site-specific DNA recombinase ...

  5. Protein primary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_primary_structure

    Protein primary structure is the linear sequence of amino acids in a peptide or protein. [ 1] By convention, the primary structure of a protein is reported starting from the amino -terminal (N) end to the carboxyl -terminal (C) end. Protein biosynthesis is most commonly performed by ribosomes in cells.

    Google's mobile Android operating system can use their own Google Lens application to scan QR codes, or third-party apps like Barcode Scanner to read both one-dimensional barcodes and QR codes. Google's Pixel devices can natively read QR codes inside the default Pixel Camera app. Nokia's Symbian operating system featured a barcode scanner, [ 28 ...

  7. Complementary DNA - Wikipedia

    en.wikipedia.org/wiki/Complementary_DNA

    Complementary DNA. In genetics, complementary DNA ( cDNA) is DNA that was reverse transcribed (via reverse transcriptase) from an RNA (e.g., messenger RNA or microRNA ). cDNA exists in both single-stranded and double-stranded forms and in both natural and engineered forms. In engineered forms, it often is a copy (replicate) of the naturally ...
