  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 .

    en.wikipedia.org/wiki/Alec_Jeffreys

    DNA profiling, based on typing individual highly variable minisatellites in the human genome, was also developed by Alec Jeffreys and his team in 1985, [20] [21] with the term (DNA fingerprinting) being retained for the initial test that types many minisatellites simultaneously. By focusing on just a few of these highly variable minisatellites ...

    en.wikipedia.org/wiki/Forensic_DNA_analysis

    Modern DNA analysis is based on the statistical calculation of the rarity of the produced profile within a population. While most well known as a tool in forensic investigations, DNA profiling can also be used for non-forensic purposes such as paternity testing and human genealogy research.

  5. Amplified fragment length polymorphism - Wikipedia

    en.wikipedia.org/wiki/Amplified_fragment_length...

    Amplified fragment length polymorphism (AFLP-PCR or AFLP) is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by Pieter Vos, [1] AFLP uses restriction enzymes to digest genomic DNA, followed by ligation of adaptors to the sticky ends of the restriction ...

    For example, minisatellite DNA is a short region (1-5 kb) of repeating elements with length >9 nucleotides. Whereas microsatellites in DNA sequences are considered to have a length of 1-8 nucleotides. [8] The difference in how many of the repeats is present in the region (length of the region) is the basis for DNA profiling. [citation needed]

    en.wikipedia.org/wiki/DNA

    In technology, these sequence-specific nucleases are used in molecular cloning and DNA fingerprinting. Enzymes called DNA ligases can rejoin cut or broken DNA strands. [130] Ligases are particularly important in lagging strand DNA replication, as they join the short segments of DNA produced at the replication fork into a complete copy of the ...

  8. Genome survey sequence - Wikipedia

    en.wikipedia.org/wiki/Genome_survey_sequence

    This approach is rapid and easy to use. It is obtained from analysis of many genomic loci flanked by Alu repetitive elements, which are non-autonomous retrotransposons present in high number of copies in primate genomes. [13] Alu element can be used for genome fingerprinting based on PCR, which is also called Alu PCR.

  9. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    This method of sequencing utilizes binding characteristics of a library of short single stranded DNA molecules (oligonucleotides), also called DNA probes, to reconstruct a target DNA sequence. Non-specific hybrids are removed by washing and the target DNA is eluted. [147] Hybrids are re-arranged such that the DNA sequence can be reconstructed.
