  2. DNA profiling - Wikipedia

    en.wikipedia.org/wiki/DNA_profiling

    DNA profiling (also called DNA fingerprinting and genetic fingerprinting) is the process of determining an individual's deoxyribonucleic acid characteristics. DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding .

  3. DNA barcoding - Wikipedia

    en.wikipedia.org/wiki/DNA_barcoding

    DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode ...

  4. Optical mapping - Wikipedia

    en.wikipedia.org/wiki/Optical_mapping

    Optical mapping [1] is a technique for constructing ordered, genome-wide, high-resolution restriction maps from single, stained molecules of DNA, called "optical maps". By mapping the location of restriction enzyme sites along the unknown DNA of an organism, the spectrum of resulting DNA fragments collectively serves as a unique "fingerprint" or "barcode" for that sequence.

    When CNN’s Tim Curran sent DNA samples to genetic testing services searching for his birth family, he had no idea it would launch him on a rravel adventure all the way to North Africa.

  6. Metabarcoding - Wikipedia

    en.wikipedia.org/wiki/Metabarcoding

    Metabarcoding is the barcoding of DNA/RNA (or eDNA/eRNA) in a manner that allows for the simultaneous identification of many taxa within the same sample. The main difference between barcoding and metabarcoding is that metabarcoding does not focus on one specific organism, but instead aims to determine species composition within a sample.

  7. Genetic marker - Wikipedia

    en.wikipedia.org/wiki/Genetic_marker

    A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species.It can be described as a variation (which may arise due to mutation or alteration in the genomic loci) that can be observed.

    Use Face, Fingerprint or PIN to sign in to AOL Entering a password to sign in to your AOL account can sometimes feel like a hassle, especially if you forget it. If your smart device is enabled with biometric authenticators like a fingerprint sensor or facial recognition technology, you can sign in with ease.

  9. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    DNA sequencing may be used along with DNA profiling methods for forensic identification [21] and paternity testing. DNA testing has evolved tremendously in the last few decades to ultimately link a DNA print to what is under investigation. The DNA patterns in fingerprint, saliva, hair follicles, etc. uniquely separate each living organism from ...
