DNK MARKERLARI YORDAMIDA G’O’ZA GERMOPLAZMASI KOMPLEKSIYASIDAN SHO’RGA CHIDAMLI GENOTIPLARNI ANIQLASH
Abstract
Dezoksiribonuklein kislota (DNK)- nuklein kislotalarining bir turi. Tarkibida dezoksiriboza, azot asoslaridan adenin (A), guanin (G), sitozin (cytosine) (C) va timin (T) hamda fosfat kislota boʻladi. Barcha tirik organizmlar hujayrasida uchraydnavroz kotli tarkibi, yaʼni uning birlamchi strukturasi har bir organizm uchun oʻziga xos va qatʼiy individual boʻlib, biologik informatsiyaning kod shaklda (qarang Genetik kod) yozilishidir. DNK ning genetik ahamiyatini dastlab O. Everi shogirdlari bilan birga aniqlagan (1944, AQSH). DNK tarkibidagi nukleotidlarning oʻzaro munosabati maʼlum qonuniyatlarga boʻysunadi.
