Idéntifikasi DNA

Tés DNA atawa idéntifikasi DNA nyaéta téhnik dina élmu forensik pikeun mikawanoh atawa nganyahokeun hiji jalma dumasar kana profil DNAna. Profil DNA dipidangkeun dina bentuk angka-angka anu bisa ogé dipaké salaku idéntitas hiji jalma. Ilaharna, tés DNA dipaké pikeun kaperluan panalungtikan kajadian kriminal atawa pikeun nangtukeun pancakaki (hubungan kolot-budak, dulur sabapa, jsb.

Najan 99,9% tina runtuyan DNA manusa sarua, sabagian leutikna anu béda bisa dipaké pikeun ngabédakeun hiji jalma ti jalma séjén, iwal dina kajadian jalma nu kembar siam (monozigot)^[1]. Profil DNA ngagunakeun runtuyan nu diulang nu gedé karagamanana^[1] nu disebut variable number tandem repeats (VNTR), utamana short tandem repeats (STR). Najan alél-alél lokus VNTR antara jalma-jalma nu deukeut duduluranana mirip, tapi ampir teu mungkin sarua.

Téhnik nguji profil DNA munggaran dilaporkeun taun 1984^[2] ku Sir Alec Jeffreys ti Universitas Leicester di Inggris^[3] anu kiwari dijadikeun dasar pikeun sababaraha databés DNA nasional. Téhnik Dr. Jeffreys mimiti dijual taun 1987 ku Imperial Chemical Industries (ICI), anu ngadegkeun puseur uji getih di Inggris^[4].
